sanitizedArguments are the arguments received on the CLI minus
those that are part of the NSArgumentDomain
For example:
sogo-tool user-preferences set sogo1 -p /tmp/creds Vacation -f /tmp/json
arguments would contain:
@"set", @"sogo1", @"-p", @"/tmp/creds", @"Vacation", @"-f", @"/tmp/json"
sanitizedArguments would contain :
@"set", @"sogo1", @"Vacation"
