- removed all asserts from the interpolation objects' Destroy methods. The condition will not be true after a failed savegame write occured.

- fixed: D_ErrorCleanup must clear 'savegamerestore'.
- fixed: Cleaning up when loading a savegame failed while restoring the thinker list did not work. There were two issues:
  * removed the asserts in GC::SweepList because they get triggered by thinkers that were not fully initialized during loading.
  * AActor::UnlinkFromWorld may not assume that the sector list has been initialized when this function is called.
