test case for #5008

[pjfanning]

I see the disabled test fail in 2.19, 2.18 and 2.17 branches and the enabled test pass on all 3 branches but this could be an issue on my side.

#5011 shows the 'failing' test fails in 2.17 branch and the passing test passes - so 2.17 and 2.19 branches have same results.

One diff from the 5008 POC is that I don't add the ParameterNamesModule.

Yes, it's all about Parameter Names module -- databind has test AnnotationIntrospector to imitate that (cannot add dependency).

But this is not an actual valid test case in that behavior is expected: 1-param auto-detection case considers this to imply "Properties" style due to existence of getValue() and named parameter for "value".

So no need for test case. Unless I guess we want to add test to show expected behavior (but we might already have one -- can't say off-hand).
