[PATCH v3] contrib: pick: bugfix when trying to show a non-message

[Mark Walters <markwalters1009@gmail.com>]

If the user pressed return on the end result status line it gave a
blank message. Modify the function notmuch-pick-get-message-id to
return nil rather than an empty message-id in this case to fix this.

This also fixes a bug in the (lack of) quoting of the id string.

v2 is at id:1352562350-8219-1-git-send-email-markwalters1009@gmail.com

As suggested by bremner make the nil return from the if clause
explicit (as that is the point of the change).
