Create the ListOfTableId and use it on NextTableProperty

CHANGELOG.rst

 =====
 - Added missing ``ActionPopMPLS.length`` attribute to fix ``PackException`` when packing objects.
 - Correct return value for ``get_size()`` when used with ``ActionHeader`` objects directly (useful for TableFeatures Properties).
+- Fix ``NextTableProperty.next_table_ids`` to correctly export only the Table IDs
