appDisplay: Only emit layout-changed when not updating pages

It is wasteful to emit layout-changed when updating pages, because
the caller (AppDisplay) already has an updated state by the time
this is called.

Only emit 'layout-changed' if the GSettings notification doesn't
come from AppDisplay updating the pages.
