Properly check empty context-sensitive collision shape

Browse Source 
The emptyCollisionShape() function only checks whether the
cached collision shape (not the context-sensitive collision shape)
is empty. In places where we use the context-sensitive
collision, we need to check the context-sensitive shape instead.
