Reconciliation, discovery and delete (TestReconTask)

Once in a while the TestReconTask.test400DeleteDummyDefaultAccount fails. The reason is, that the discovery deletes the dummy account but does not unlink it from the user. It does not unlink it, because the user is not set as focus in the lens context. I do not know why that happens. Looks like the SynchronizationService does not set it.

This only happens once per approx 130 test runs.
