Cleanups to fix bugs in the VM count API functions.

- Urgent voicemails were not attached, because the attachment code looked in the wrong folder. - Urgent voicemails were sometimes counted twice when displaying the count of new messages. - Backends were inconsistent as to which voicemails each API counted. - Unit tests added to verify behavior in the future.
