Fix viless search origin

When searching without vi mode the display is no longer reset when the
user hasn't jumped between matches at all. Since there's no reason to
confirm the search, we shouldn't just reset the viewport without a good
reason.

The search is now also restarted completely when the entire search regex
is deleted. While this doesn't reset to the original viewport position
if the user has jumped between matches, it should make things feel a
little less arbitrary.

Fixes #4020.
