When picking, there is no way to remove the picker UI except picking
away from an actor. However, when this happens an exception was raised
due to a silly bug. This also changes the behavior now so we press
escape/q/e keys it will no longer display the picker UI. Also fixes a
bug with the wxPython scene for VTK 9.x.
