Title: 2.5 - Dbosource bc fix

@dereuromark Pointed out that recent changes in DboSource have caused community plugins to break because of the additional type hints. Removing those typehints should address the problem. I've changed the method to return '' when $LinkModel is null as it would generate a warning previously.
