RFR: 8273410: IR verification framework fails with "Should find method name in validIrRulesMap"

[Christian Hagedorn]

The IR framework treated a `@Check` method as `@Test` method instead of the `@Test` method itself at IR matching time resulting in an internal framework exception.

While writing some tests for checked test I've noticed that a missing `@Arguments` annotation is not reported as `TestFormatException` but with a `RuntimeException` later when invoking the method in question. I also added the missing check for it.

Thanks,
Christian
