ZVISION: Don't change location when coming back from ScummVM save dialog and do change location when coming back from restore dialog

Fixes bug # 6771

We don't need to change locations, since we use the ScummVM save dialog instead
of the original one (which is actually a location). Instead we just need to reset _nextLocation to
_currentLocation so the engine can stop trying to save. If we change locations, the
StateKey_LastWorld/Room/etc. end up being overwritten with the current room. So if a script
refers to location 0, 0, 0, 0 (aka, the last room), the engine will try to change location to the same room.

On restore, we have to force a location change, just in case we restore to the same room. (Since the logic
will only do a location change if _nextLocation != _currentLocation)
