[PATCH 2/2] contrib: pick: add a target message for pick

[Mark Walters]

This adds a target message for pick which it will jump to when (if) it
appears. It adds the target to notmuch-pick-from-show-current-query so
that pick goes straight to the message that was current in the show
view and it adds target to notmuch-pick-refresh-view so that the
current message is preserved.
