/**
 * The test of OrganizationCommandHandler is a bit more involved than the average AxonTest. The reason is that the fixture is only
 * supporting a single repository and we need three different Aggregates to perform all tests (Organization need a ServiceSpecification to
 * create a ServiceInstance. Hence the setup of to "Mocked" repositories that are used for handing us the prerequisites.
