Change @dataprovider to static in CallableResolverTest

Here we don't need mocks but we are testing instance methods directly, the only thing I could see to do here is move the cases into the test method and run them via a foreach loop.

Pity that we can no longer use a dataprovider here, but given the choice to make these static methods, this seems sensible. Thanks

Committed/pushed to 11.x, thanks!

This doesn't cherry-pick to 10.3.x, moving to 'to be ported', since we might as well do that at some point.

Redid the patch for 10.3.x.

10.3 patch looks fine.
