Removes updates of the toolbar triggered by BVC

This CL removes the update of the toolbar view triggered by
-updateToolbarState, called by BVC. This call is not needed as the
callbacks are done in the ToolbarMediator.
It allows us to remove this method once the updates of the omnibox are
moved to the locationBarCoordinator.
