do not throw DisposedException when inside a dispose() method

There is no need to do this, as the documentation of
css.lang.XComponent::dispose at

udkapi/com/sun/star/lang/XComponent.idl

states:

After this method has been called, the object should
behave as passive as possible, thus it should ignore all calls

Otherwise, the effect of throwing here is mostly to disturb the flow of
logic in caller code, preventing other parts of teardown from proceeding
smoothly.
