list view doesn't use correct sorting

It appears that _refresh_apps_with_apt_cache() uses return self.app_view.get_sort_mode() and that returns the wrong
value.

The reason is that display_matches() updates the combobox but get_sort_mode() is called before display_matches so
the combo is still using the old value.

it seems that replacing
  self.set_sort_method_with_no_signal(self._SORT_BY_TOP_RATED)
by
  self.sort_methods_combobox.set_active(self._SORT_BY_TOP_RATED)
in _use_combobox_without_sort_by_search_ranking solves this problem, but it feels slightly dodgy so probs isn't a good solution

This bug was fixed in the package software-center - 5.2
