(Temporary) Fix corner collision issue

Changelog:
- When player move diagonally into a corner, collision is missing.
  This is because collision is resolved one-by-one and will not
  move the player if the new position still causes collision. In this
  literal corner case, player will not be moved as the player collide
  with both solids and resolving in either direction would still result
  in collision in the new position, unless both is resolved at the same
  time.
  Temporary 'fix' this by not checking the new position. No real idea
  on how to solve this for now.
