stage-view: Bump fake swap ready notify callback priority

Browse Source 
This will become important when dispatching happens from a frame clock
driver, where the driver itself triggers from a GSource. If the driver
source has a higher priority, we'll risk dispatching before the frame
clock has returned to a state expecting to be dispatched.
