Surprisingly, the docs claim g_mime_utils_header_decode_phrase has no
error conditions, so I guess this is OK.

On the other hand, _notmuch_message_gen_terms does return a status. I
agree that currently this status is not useful, but that could change in
the future.  I also agree that the existing code does the same thing in
a few places, but I think it's better not to introduce more.

We'll need a test or two before we introduce a core change.

Any objections to the list: syntax?  The only issue I see is that at
some point we will probably add a generic header search syntax, and this
implicitly says list-id is more important/common than other headers.
