Bypass move_effect check if force true when moving vertically

[Fris0uman]

Summary

None

Purpose of change

Fixes #60896

Describe the solution

Falling while downed would get you in an infinite loop because the downed effect never clears and thus you never get past the move_effect check so you never actually move

Describe alternatives you've considered

Bypass the check when force == true which is the case when falling and make sense, if we're forcing the movement we don't care about move effects

Testing

Teleport in the sky one > fall and get downed
Teleport a second time
> before patch get into infinite loop
> after patch get to the ground no issue

Additional context

I think this makes the situation better, but looking over what happens in move_effect, we need a better solution for canceling effects when they no longer make sense.

Maybe pass an enum saying what kind of movement it is into move_effect() so it can decide whether it should cancel it.
