The 'new version' of the PlanarFigureInteractor uses the property "initiallyplaced" to determine if the figure has been placed or not in the method CheckFigurePlaced().
This check has been introduced in the porting of the PlanarFigureInteractor to the new interaction-framework.
This check is not necessary and causes massive problems with the interaction of PlanarFigures that have been serialized BEFORE the property "initiallyplaced" has been introduced.
As this check is unnecessary, we can remove the check without a problem.
