bachinger 4a9cf7d069 Do not assume a valid queue in 3rd party sessions
This change fixes an issue that can be reproduced when
a controller `onConnect` creates a `QueueTimeline` out
of the state of a legacy session and then `prepare` is called.

`activeQueueItemId`, `metadata` and the `queue` of the legacy
session are used when a `QueueTimeline` is created. The change
adds unit tests to cover the different combinatoric cases these
properties being set or unset.
