Open Calls application when incoming phone call wakes up the system
Epic: https://source.puri.sm/Librem5/use-cases/issues/1, https://source.puri.sm/Librem5/use-cases/issues/95
(this is not yet easily testable as we don't use suspend/resume yet)
When the system is in S3 suspend and receives a phone call, it is woken up by the WWAN modem. The Calls application isn't opened though - at least not when the lockscreen had been shown before suspending. That's the only real test I can report for now:
When the lock-screen had been shown during suspend, it is shown when waking up too.
I'll add more details and instructions how to test, if applicable.
