[PATCH] lib: update notmuch_tags_get example to reflect api change

[Austin Clements]

Sorry, I replied to the wrong one.  This one LGTM.

(BTW, for future reference, it's helpful if you send later versions in
reply to the first version so that they're grouped in threads.  Sorry
that the documentation on notmuch's coding conventions is so scattered
and lacking.  We're working on it.)
