8241737: TabPaneSkin memory leak on replacing selectionModel

[arapte]

TabPaneSkin adds a listener to SelectionModel.selectedItemProperty() which holds the SelectionModel from being GCed. Fix is to add and remove the listener when a SelectionModel is changed.

If the fix looks good, We can change all the getSkinnable().getSelectionModel() calls to use the new class member selectionModel.

The fix seems safe to cause any regression. Enabled an ignored test that was added as part of fix for JDK-8241455.
