I suppose the error returned by
notmuch_message_remove_all_properties_with_prefix() is the value that we
should return.  I've switched this to a simple goto DONE in my gitlab
repo.

However, i note that an error here will be (from the outside)
indistinguishable from an error in _notmuch_database_ensure_writable or
_notmuch_message_remove_indexed_terms() immediately above, so i've added
a small TODO anyway.

thanks for the reviews, bremner.  please keep them coming!  (or tell me
when you're done so i can send v7 to the list with resolutions to all
these nitpicks)
