Resolves fdo#87123: Impossible to create a form with wizard

Quoting Noel:
"
The original block of code looked like this before my changes:

MethodInvocation windowHidden = new MethodInvocation("windowHidden", this);
xWindow.addWindowListener((CommonListener) getGuiEventListener());
String dialogName = (String) Helper.getUnoPropertyValue(xDialogModel, PropertyNames.PROPERTY_NAME);
getGuiEventListener().add(dialogName, EVENT_ACTION_PERFORMED, windowHidden);

which is clearly bogus, since "actionPerformed" is not an event on the XWindowListener interface.
