Unbreak the "notmuch setup" command.

The recent addition of support for automatically adding tags to
new messages for "notmuch new" caused "notmuch setup" to segfault.
The fix is simple, (just need to move a destroy function to inside
a nearby if block).

Did I mention recently we need to add a test suite?
