emacs: put the last search on top of recent searches in notmuch-hello

Notmuch-hello stores a list of recent searches.  Before the change, if
a search from this list is repeated, the recent search list is not
changed.  The patch makes repeated recent searches move to the head of
the list.  I.e. the last search is always on top of the recent search
list, which is what one would expect from a history list.
