Paraya 6 JAX-RS invalid transaction name + no span captured with @Trace

This was initially reported in our forum:

https://discuss.elastic.co/t/problem-with-distributing-tracing-for-jakarta-10-and-payara-6/372920/6

With the provided test application in https://github.com/ciment7/jakarta-test we can reproduce the following symptoms:

- the first execution of the jax-rs resource is properly named (1)
- the second and following executions of jax-rs are named from the servlet transaction (2)
- no extra span is being captured for the method annotated with `@Traced` (3)

For 1) and 2), the issue seems to happen because in the first case the servlet transaction wraps the jax-rs resource execution, and in the second case the jax-rs invocation is made without parent servlet transaction, which is something that we don't support as described in https://github.com/elastic/apm-agent-java/issues/1752 issue.

For 3) this is probably a related issue but I have not found any hint of what could be wrong here.
