tests: proper handling of event loops

Event loops have to be closed properly, otherwise pytest will throw a
warning / error. Disconnecting clients and closing the server is
important for that, as well as stopping tasks.
Additionally, I had to add loop_scope parameters to share the event loop
throughout modules which all use the same pydase.Server instance.
