Apply is_ceiling/is_wall swap fix to 2D move_and_slide (minus explaination)

As it turns out, is_ceiling would be true when hitting a wall,
 and is_wall would be true momentarily when hitting a ceiling.

This makes a tiny one-line change to fix that.
Without trying to explain the code for anyone else having to
 mess around with it.
