Remove property chains inferring develops_from over part_of.

[balhoff]

This PR removes two property chains:

• part_of o develops_from -> develops_from
• develops_from o part_of -> develops_from

We noticed these causing some unexpected inferences in GO, for example protein-containing complex being inferred to develop from an anatomical entity. These should be in RO anyway, if they were to be accepted.

I also deleted these chains from the cl_import.owl. I looked at the CL source, and I think they got these via Uberon, so hopefully that bit of ontology autophagy will be cleaned up when both have releases.

I computed a reasoned file using this command: robot reason --catalog catalog-v001.xml --exclude-duplicate-axioms true --remove-redundant-subclass-axioms true -i uberon_edit.obo -o reasoned-new.ofn

and compared before and after the changes using robot diff. Somewhat unexpectedly, I didn't see any classification differences.

Just spotted this. I think the second of these two property chains is kosher and should be in RO.

@dosumis I think that chain leads to weird statements:

'neuron projection bundle' develops_from 'multicellular organism'
'flask cell' develops_from 'organ'
'interrenal gland' develops_from 'abdomen'
