When PhysicsHold is installed an enabled on a base, a few bugs occur. The most annoying one is that hatches from inside the base cease to function with FreeIVA. This is because the vessel appears in a packed state.

Since you can only open hatches in FreeIVA mode on a packed vessel you are actually inside (and the bug does not occur from outside), simply checking if we are the active vessel before yielding null should suffice.

@R-T-B Does CheckForConnection run again when you enter IVA mode? Because otherwise you could end up with hatches that aren't connected because this ran before the active vessel was unpacked (I think).

I've been using this patchset for a month in my personal save now and have yet to see an unconnected hatch on an active Vessel, so I don't think that happens like that. But I admitedly have not tested literally every scenario. Any suggestions on how to do this better would be welcome.
