If the `Automatic Constraint` modifier was activated while an axis
constraint was already set, the orientation used would be the default
orientation of the mode and not that of the scene.
This was because the `initSelectConstraint` function was not called in
this case and the `Automatic Constraint` mode was enabled by other
indirect means.
So the solution is to call `initSelectConstraint` in either case and
remove these "indirect means" of enabling `Automatic Constraint`.
