Paused actor physics resume when switching to another actor

[CuriousMike56]

• Spawn two actors
• Press END key to pause physics for current actor
• Switch to the other actor, previous actor's physics will resume

Also recently noticed the skeleton debug view disables itself when switching actors, possibly related?

Here is the culprit (and yes, skeletonview related): https://github.com/RigsOfRods/rigs-of-rods/blame/master/source/main/physics/ActorManager.cpp#L745-L746 - it broke in https://github.com/RigsOfRods/rigs-of-rods/commit/9431e1b508575c40498ed9becd8a0385a3b95463 - I needed to reset the paused/skeleton after decoupling from the player vehicle. Doesn't make big sense for paused state but it's important with skeleton view.
