Fix the ability to retrieve voicemail messages from IMAP.

A recent change made interactive vm_states no longer get
added to the list of vm_states and instead get stored in
thread-local storage.

In trunk and all the 1.6.X branches, the problem is that
when we search for messages in a voicemail box, we would
attempt to update the appropriate vm_state struct by directly
searching in the list of vm_states instead of using the
get_vm_state_by_imap_user function. This meant we could not
find the interactive vm_state that we wanted.
