RecentTabHelper: Move URL checking logic into DidFinishNavigation.

We need to prevent saving certain types of pages, moving into DidFinishNavigation
prevents the SnapshotController from even starting; this is better than waiting
for the right moment detector to fire before we check that snapshots are OK for
this page.
