lib: Perform the same transformation to _notmuch_database_find_directory_id

Now _notmuch_database_find_directory_id takes a flags argument, which
it passes through to _notmuch_directory_create and can indicate if the
directory does not exist.  Again, callers have been updated, but
retain their original behavior.
