[PATCH] contrib: pick: bugfix. use notmuch-show-only-matching-messages rather than prefix

[Mark Walters <markwalters1009@gmail.com>]

Previously pick set a prefix argument prior to calling show in the
message pane to tell show to only show matching messages. This sets
notmuch-show-only-matching-messages instead which is much cleaner and
will work even if the user has configured show to default to showing
only matching messages.
