notmuch_message_get_filename: Support old-style filename storage.

Browse source 
When a notmuch database is upgraded to the new database format, (to
support file rename and deletion), any message documents corresponding
to deleted files will not currently be upgraded. This means that a
search matching these documents will find no filenames in the expected
place.

Go ahead and return the filename as originally stored, (rather than
aborting with an internal error), in this case.
