Don't emit predicted_navigation for reloads at all

When we reload a page because of a config change, we won't get another
titleChanged signal (at least sometimes).

Also, the predicted_navigation signal is worthless when reloading anyways, as
we're going to load the same URL and not something different.

Fixes #3718
