Do a comparative sync between local and server voicemails.
Currently a sync will completely wipe local voicemails and replace them
with the server voicemails. Instead, we will do a comparative sync to be
less disruptive to the user, and properly notify when a new voicemail is
available on the server. The changes are as follows:
* Rename DirtyVoicemailQuery to VoicemailsQueryHelper to handle all
queries related to the voicemail provider.
* Implement the comparative sync logic in OmtpVvmSyncService
* Fixed bug when receiving mailbox update sync message in
WrappedMessageData (tried to parse a field that did not exist)
