Cancel manual animation if LauncherState changes during drag.

Previously, the following would cause the All Apps panel to appear
in NORMAL state:

1. Start dragging to all apps
2. During the drag, something sets Launcher to NORMAL
3. Release finger  -> animation to all apps completes, but state
   is still NORMAL

Side effects of this:
 - On large screens, All Apps draws its background on Launcher's
   ScrimView only if the current state is All Apps. So in this
   case, the apps just floated above the workspace.
 - On handheld, touches are handled by workspace even though you
   can see the All Apps list. So e.g. if you swipe down, the
   notification shade appears rather than all apps panel hiding
   (although it seems this touch issue was addressed separately).

I'm not sure if this is the main/only case of this state mismatch
happening, but verified with local async state changes that this
could in theory happen. We haven't been able to organically repro
the bug reliably. That being said, it feels plausible that a well
timed screen lock during the all apps transition could also hit
this case.

Demo videos with hard-coded state change to NORMAL 2 seconds after
you start swiping up to all apps (note I release my finger at the
end of each video):
