Omnibox: Don't Force Notify Default Match Changed When Expiring Old Matches

Previously, we force the autocomplete controller to notify the edit model that the edit default match has changed when we expire old matches, even if the default match didn't change.  This removes that forcing code.

I tested it on Linux for a bit.  Everything looks fine to me.  I didn't see any jankiness.  Let's hope the other platforms are the same.

TEST=by hand playing with the omnibox on Linux for five minutes
