Do not defer wm display logic when called from am.
Currently we process any remove/add/change logic from the activity
manager to the window manager through a handler message. This opens
the possibility of the activity manager requesting display state
from a window manager that is a step behind.
This change modifies the call behavior so that these changes are done
synchronously between the two managers.
