add sanitizedArguments to SOGoTool

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"
