Update battery saver suggestion to go to right page

Now that there are several different versions of automatic
battery saver, this notification should just take you to the
battery saver schedule page rather than setting it to 15%
automatic triggering.

Test: adb shell am broadcast -a PNW.autoSaverSuggestion
      --ez extra_confirm_only false
