Fix crash from folding/unfolding

This is fundamentally caused by the phone device profile not having task bar related attributes, which crashes in icon alignment animation. We had resolved it by skipping this animation based on isPhoneMode check. However, we passed in launcherDp instead of taskbarDp (from TaskbarActivityContext) which doesn't always have the most up to date information in race conditions (e.g. repetitively fold/unfold)

Fixes: 311431054
Test: repetively fold/unfold, make sure it doesn't crash
