resume: fix recents showing up when waking the device with the home button

The previous fix, resolved the problem most of the time, but the home
long press would still happen once in a while during resume from RAM.

This is probably still somewhat dependent on timing but the notifyKey
runs immediately first thing after resume, so this fix should solve the
problem completely and it should be enough.
