There is a use case where this has caused crashes:
A message was hard-deleted using an IMAP client, this is the first
message you deleted in that folder and you have cleared offline
items in the client so a full sync is asked by upper layer.
In that situation, the SyncLastDeleteChangeNumber version property
is not set and return 0 in [getDeletedKeysFromChangeNumber:andCN:inTableType]
making OpenChange to crash while it is asking for deleted fmids
since a given change number.
This is a regression from 18d7070c4a.
Sometimes we're trying to get the `objectVersion` of a calendar message,
but this message's entry is not in the cache. The method
`synchroniseCache` won't work in this case, so we try to force the
synchronisation of that particular message in order to get the change
number before aborting.
And perform the real IMAP operation on save method as described by
[MS-OXCFXICS] and [MS-OXCMSG] Section 2.2.3.3, these operations must be
committed when SaveChangesMessage is called.
As it is expected by Outlook to increase the change number when
performing the `SetMessageReadFlag` ROP, if it is not done, the client
tries indefinitely to store that.
Happened in an imported vevent from Mozilla Thunderbird.
The crash was:

This method does not longer returns true if the content id
was a empty string.
In some case the old false positive triggered the removal of
attachments when sending messages.
When returning contacts we have to supply also the domain field.
Because in a multidomain environment UIDField is unique only in
the domain so an user must be identified as uid@domain.
So when creating http requests from client side, we have to use
uid@domain instead of only uid so the SOGoUser created on server
side when parsing the requests is created properly.
The operation RopFastTransferSourceCopyTo calls the available
properties for a message using the instance method. It seems the
preferred method by Outlook to synchronise a FAI message. OpenChange
calls the message to get the available properties, so the instance
method is called. As it is specialised to return the custom hack
FAI properties, we have to call that class method instead of using
generic one available at NSObject (MAPIStoreProperties) class.
This avoids crashing the Outlook client after we synchronise the
calendar folder after changing the timeframe view (eg from day view
to month view).
A user can edit/delete a card from a system addressbook if included in
the "modifiers". Enable the delete/move options of the contextual menu
in this case.
Fixes#3342
The folder names are encoded through the `asCSSIdentifier` and
`stringByEncodingImap4FolderName` functions when we store them as folder
keys. In addition, the prefix "folder" is added to the key.
The order in which these operations were done when storing the folder
keys (and reverted when retrieving them) wasn't consistent trough the
code. This led to problems such as creating twice a folder with a digit
at the beginning of its name.
The folder name goes now through the following operations when being
stored as a key (the retrieval reverts these in the reverse order):
* `stringByEncodingImap4FolderName`
* `asCSSIdentifier`
* Add "folder" prefix
