Timo Tijhof 7b8eed957f ve.ui.TextInputWidget: Fix TypeError when config is undefined
Parameter config is optional (both in the parent class and here),
this subclass forgot to add the fallback.

Though in a plain subclass the local fallback isn't needed
(parent class takes cares of it), in this case it is needed
since the constructor directly accesses config.multiline etc.
