Remove QS initial tooltip

Removed from QuickStatusBarHeader and from quick_status_header_info. The
tooltip read "Touch & hold icons for more options"

Did not remove the string in case it ends up being needed.

Test: manual, system restore does not show tooltip
Test: manual, turning on alarm and switching ringer behaves as expected
