add test to check if any object_properties in dictionaries are obsolete

[nlwashington]

I just noticed that at least one of the identifiers that we are currently reliant on in our cypher queries is now obsoleted in GENO. it is possible that other object properties that were it's children are also obsoleted. These are in a dictionary in the dipper code, and leveraged when making the triples.

There should be a test that iterates through any relevant dictionaries and makes sure that the object/annotation/data_properties are still valid.

This will probably mean loading the ontologies into a local graph and figuring out if they are deprecated/obsoleted.

@jnguyenx there probably ought to be a similar test performed during a scigraph load that errors/warns if obsoleted properties (edge types) are used.
