ekrctb 6d0dc62502 Make sure latest catcher position is used for catching logic
A replay frame processed in CatchInputManager is applied to catcher in `CatcherArea`.
The catcher position is then used for the catching logic for each hit object under `HitObjectContainer`.
Thus, if `HitObjectContainer` came before `CatcherArea`, the replay input is delayed one frame.
That was one reason why the catch autoplay misses hit objects (especially when fast-forwarded).
