PouleyKetchoupp 1f816979f6 Fix SoftDynamicBody3D memory corruption when switching mesh at runtime 
When switching the mesh at runtime, the physics server wasn't properly
updated with the new mesh. Now we keep track of the soft body mesh to
make sure everything is properly initialized on pre-draw.

Also cleaned a few things around private methods.
