Panic when user calls all x all only a predicate argument that doesn't exist in ontology

[justaddcoffee]

This panic happens when a user specifies only a predicate that doesn't exist in ontology (I'm using the try_rwlock_instead_of_mutex branch, since it looks like this will be merged soon-ish). This is what happens on the Oak side:

Not a problem if they specify one that exists and one that does not:

(rustsim) ~/PythonProject/ontology-access-kit implement_all_by_all_in_semsimian $ time runoak --stacktrace -i semsimian:sqlite:obo:bfo similarity -p i,doesntexist .all @ .all > /dev/null

I think we probably just need to check for this in update_closure_and_ic_map here and also need a test on the semsimian side, something like:

let pw = semsimian.all_by_all_pairwise_similarity(subjects, objects, a_single_predicate_that_doesnt_exist)
// assert there is no panic
