This PR solves issue with tests in the SecurityBundle: current structure of tests force to repeat the same test case for every format (PHP, XML, YAML) even if it doesn't depend on them (see #8782).

It is an addtion to my previous PR https://github.com/symfony/symfony/pull/7699

There is no need to check again previously checked sub-trees.

In our tightly coupled services graph, this circular reference check runs avg 1,5ms, before that: 100ms

Made fragment URLs relative instead of absolute by default

This fixes a regression introduced with the new fragment system where fragment URLs were generated as absolute URLs. As per the ESI spec, there is no need to generate an absolute URL and this can even be problematic when dealing with internal sub-requests in a more "complex" hosting environment.
