Fix T80937: Changing the contrain axis does not return to the scene orientation

This was the behavior in old versions of blender.

During a transformation operation, when pressing a contrain key, the chosen
orientation is that of the scene.

If you press the same key, the orientation changes to Global or Local.

However, if you choose another contrain axis with the orientation changed,
the orientation does not return to the set for the scene.

It remains Global or Local.

Now when changing a contrain axis, no matter what the current orientation is,
it always returns to the scene orientation.
