Force extruder position to stick during retrieval of property.

Otherwise other parts of the stack(s) could have another value for limit-to-extruder, depending on if the user updates the chosen extruder (for example for support) quickly enough that we're in the middle of the operation. (Locking would probably more complicated, since we not only need a recurrent lock, but a lock on a few but not all classes based on a method call....)
