Add failing test for RemoveUselessReturnTagRector

Psalm allows prefixing of tags. Usually these would provide refinement on top of the type so should not be removed

Seems legit 👍
Please provide fix so we can merge it

Any pointer? I can't get the project running very well locally so it's difficult to play about.
Is it treating the @psalm-return tag as a normal @return tag?

Probably check the name on the ReturnTagValueNode. It should be in the removal method.
