The PubSub backend does not give any guarantees about when a message will be re-delivered after seeking back to a snapshot, it will only be delivered "eventually". That causes flakiness in the snapshots test. Since the test cannot wait for an indefinite amount of time, this commit removes it in order to not randomly break the CI builds.

Closes#4031.
The title says it all - this PR adds the missing system tests mentioned in the issue description:
Creating / seeking snapshots.⬅️ Removed, because the server only guarantees eventual re-delivery, and a test cannot wait for a fixed amount of time, causes flakiness.
