Check that all distances are positive or zero
Issue:
https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/clustering.gmi
* gn3/computations/slink.py: check that all distances between the 'somethings'
are all either zero or positive.
* tests/unit/computations/test_slink.py:
* Remove data with all distances positive or zero, since it would fail the
test
* Change the expected message to more closely correspond to the business
logic
