We already have the full path at some point so there's really no need to rebuild it once again, especially since the code was incorrect as it was adding the /q/ prefix always if it wasn't there in the path.

It's perfectly valid to not have /q in the path, for instance if you set quarkus.smallrye-health.root-path to /something/else.

I added a new test based on the report in addition to the ones we added recently for related fixes.

Fixes #46040
