Potential infinite recursion in list_from_graph_collection

[jgonggrijp]

See https://github.com/UUDigitalHumanitieslab/EDPOP/pull/195/files#r1831499232. While this issue is unlikely to come up on the short term, this could easily change. This is the kind of thing that should be fixed in combination with a regression test.

If the RDF data contains a looping list (which would cause infinite recursion), what should happen instead?

[jgonggrijp]

Pretend that the list ends after the element that closes the loop?

So:

[1, 2, 3, 4, 5, 1, 2, 3, 4, 5, ...] --> [1, 2, 3, 4, 5]
