Change assertions in templated normal test to more realistic ones

[holly-cummins]

This is a tiny little change, just pulling some standalone content out of #34681. One of the tests I added a while ago (which is still disabled until #27821 is fixed) checks that even if you don't have a @QuarkusTest annotation in your test, you still see instrumented bytecode in your test class. I don't think that's a realistic expectation, so adjusting the test to give it a better change of passing when it is enabled.
