Fix bindApplication starting activities late
With the attachApplication split introduced in
I659f2083f460701d858ebb7a8af9fa748ff4bfe9 apps send
a finishAttachApplication back to the system after
their initialization (Application#onCreate). The system
then dispatches Broadcast, Service and Activity starts
to the app. The delayed dispatch of Activity has 2 side
effects:
1. Apps could post messages on their main thread that will
run before activity start message which could slow down their
ttff.
2. The setFocusedApplication call is delayed and the system
doesn't know the focused application until after app init.
To mitigate this, we dispatch Activity start early before
app init.
