[FELIX-3910] added testcase which tries to reproduce the problem described in the FELIX-3910 jira issue.
For now, this test is incomplete because the paxexam version we are using is an old one and is using an old
felix framework, which does not fire a FrameworkEvent when it catches some exceptions fired by "service changed" listeners.
