Fix regression where Installed apps category wasn't sorted alphabetically

Fixes a regression where items in the "Installed" category weren't sorted alphabetically (if there's no search). We applied the popularity sorting even when the search string was empty, which shouldn't have been the case.

Added manual test, since the applications are sorted according to current locale which is non-trivial to check in bash.

Looks correct

+Sort order
+==========
+Tests that the sort order of the "Installed" category is alphabetical.
+
+#. Open the Dash and switch to the application lens.
+#. Make sure that the search string is empty.
+
+Outcome
+  The "Installed" category should be shown and the items within should be sorted alphabetically (respecting sorting of your locale).
