Fixes getting the wrong app transition going home after minimized (1/2)

Fixes getting the wrong app transition going home after minimized (1/2)

This is a side affect from ag/2125707. When minimizing and unminimizing
back to home would cause the same affect in the bug, where the app
transition is from activity to activity and not app. The issue was a
"updateAllDrawn" is normally called at the end of the surface
transaction and therefore removing this call (that would run inbetween
the transaction) should fix prematurely calculating the app transition
before setting the wallpaper target.
