Problem:
renameConstraint() previously implemented exclusively in SketchObjectPyImp.cpp,
will change the Constraints property without updating the solver. A prospective
drag operation would rely on a deleted pointer constraint which leads to the
crash.
Solution:
- mark the solver status as needing an update
- leverage new through sketchobject r/w interface to ensure solver is synchronised
before the temporary move operation starts
Bonus:
move the core of the function to SketchObject.cpp so that input data validity
check on constraint change is inhibited.
