application: don't remove providers from screen when finalizing

Browse Source 
When finalizing the application, it is possible that the main window
had already been destroyed and the Gtk+ CSS machinery to stop working.
We currently try to remove the CSS providers from screen when finalizing,
which (i) has no effect, and (ii) causes a segfault.

Fix that by simply destroying the CSS providers, and not trying to
remove them on finalize.
