Export citations exports citations also for deleted datasets

[bernt-matthias]

Describe the bug

If I export citations from a history I also get citations from deleted datasets. I noticed this for the tool Split file to dataset collection. See this history https://usegalaxy.eu/u/maze/h/unnamed-history-4

Galaxy Version and/or server at which you observed the bug Galaxy Version: usegalaxy.eu so I guess 22.05 Commit: don't know

To Reproduce

Export citations for history linked above

Expected behavior

Only non-hidden and non-deleted datasets are used to get citations.
