This fixes the warning:

TestProvider::TestProvider()
: Glib::ObjectBase( typeid(TestProvider) )
{
}

You need to call the ObjectBase constructor with a custom type name in
order to actually register a custom GType. This is admittedly awkward.

We don't register a custom GType for all derived classes because it is
usually unnecessary and possibly problematic/inefficient and b) I don't
think we figured out how to do that. Maybe we should.
