Revert "Don't show global actions if already handled"

This reverts commit 62b08743.

Reason for revert: The tests are failing consistently now, not just flaking. The problem is that `adb shell input keyevent --longpress 26` doesn't open global actions dialog after a reboot. After the dialog has been opened the first time, it will start working.
