[PATCH (corrected)] 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.
---
The previous version had an extra ). The version I was testing had the
fix but git didn't; oh well.

Best wishes

Mark
