RecentTabHelper: adds DVLOG and reload unit test.

This change adds many DVLOG entries to RecentTabHelper to help debugging
it when needed. This is a debug-build-only change so the added strings
should not affect release binary size.

The new reload test checks that this kind of navigation is properly
handled as a full reload of the page (as opposed to same-page
navigations which are "ignored" as loads).
