  [IMAP] Fix message retrieval issues when identical mailbox names were defined in separate contexts.

  There was a fix put in a while back so that an X-Asterisk-VM-Context message header was
  added to stored IMAP voicemails. This would allow for us to differentiate if the same
  mailbox name was used in multiple contexts. The problem still left was that not all places
  where messages were retrieved actually attempted to use this header for information when
  retrieving messages. This commit fixes that so that MWI and message retrieval from VoiceMailMain
  work as expected.
