test(authorization): Optimize authorization tests

When installing the Keycloak extension, drop the `createRealmPerTest`
flag. The additional isolation is no longer needed, since no roles in
Keycloak are manipulated during test execution. An initial setup of test
users used by the test cases is sufficient. So, setting up the realm for
every test case can be avoided, and the tests can be made a bit faster.
