We need to have transforms from passive objects if they are animated or driven by parent relations. This is not immediately obvious as the object transform matrix will still be available, it is just one frame behind in some cases. Fixed dependency cycles if there is a constraint between two rigid bodies. Because bullet keeps track of its simulated bodies, we do not need to supply objects transforms as bullet should already have them. I need combine these two fixes because otherwise we will get depsgraph warnings that nodes are missing that it expects to be there.
