Make sure the device route to HOME when OneTouchPlay is triggered.

Note that we still need to discuss if this is the expected bahavior.
For example when the device was on HDMI2 before TV button is pressed
to turn TV off.
When user press TV button again to turn TV on, should the device
trigger OneTouch to grab Active Source or stay in the same input.

Right now it trigger One Touch so it should route back to Home.

Test: local tested.
