VPLAY-11854 Webprocess crash AampDRMLicenseManager::createDrmSession

Reason for change: trigger the fake tune only when the device transitions from DEEPSLEEP to ON/STANDBY, we can make sure that HDMI is in the expected state and the playback should work as expected.
Test Procedure: updated in ticket
Risks: Low
