Update IRIs for 'qualifier' and 'quantifier' association properties

[mbrush]

The has_qualifier and has_quantifier properties that hang from some associations were originally created with a GENO namespace, but have since been ceded to SEPIO where they are more in scope. The following two property IRIs are seldom used in our data, but where they are they need to be updated throughout the dipper code:

1. Replace GENO:0000580 with SEPIO:0000144 (has_qualifier)
2. Replace GENO:0000866 with SEPIO:0000232 (has_quantifier)
