HeadsUp: Only remove heads up if attached to window

Attempting to remove mHeadsUpNoficiationView from the window manager
when it is not currently attached will throw an IllegalArgumentException
so we check if it is attached and if so remove it, otherwise carry on.

frameworks: set default expanded desktop style

On a fresh boot, a user can add an expanded desktop tile. They can also
add it to their power menu. But until they go into Display -> Expanded
desktop style and set it to something other than disabled, it won't show
up anywhere.

Since the user has to toggle expanded desktop, let's use a sensible
default and avoid the extra step.
