special case TypedItemList in preparation for tdf#79250

Seems a Sequence<Any> property was never supported in the
qadevOOo/tests/java/ifc/beans/_XPropertySet.java addPropertyChangeListener()
tests, where the property has to be changed in ValueChanger to pass the test.
However, simply generally adding a value to an empty sequence does not work as
it would break other tests in turn, so special-case it to the TypedItemList
property. This is all fubar.
