Diagrams depends on all containing vocabularies

[MichalMed]

I'm not sure whether this is bug or feature.

Reproduction steps:

• open OntoGrapher with two vocabularies, e.g.
  ?vocabulary=https://Fslovník.gov.cz/generický/test1&vocabulary=https://slovník.gov.cz/generický/test2,
• create an empty diagram,
• try to open OntoGrapher with only one of those vocabularies, e.g. ?vocabulary=https://Fslovník.gov.cz/generický/test1,
• you get an empty page with error in console:

If I delete triple connecting the vocabulary to diagram (přílohový-kontext), then it works fine. I suggest this behaviour is OK as the mission control creates copies of each vocabulary, but with the canonical versions it does not work.

I can't reproduce the bug on current main branch using slovník-test data - all that happens is the missing vocabulary is represented as a read-only vocabulary. If I delete the cache from the database, it just doesn't load, but there are no errors you describe. Can you send your testing data and commit version used, please?
