delete subclass-superclass relationship for 'hepatic duct intra/extrahepatic part' terms

[cindyJax]

"hepatic duct intrahepatic part" [UBERON_0005605] has a super class of "intrahepatic bile duct epithelium" [UBERON_0004823] which appears to be an error.

Likewise, "hepatic duct extrahepatic part' [UBERON_0005604] has a super class of extrahepatic bile duct epithelium [UBERON_0004822] which should be removed

Looks like this was caused by being too over-eager to align with EHDAA2, which has a tendency to see all ducts as epithelia. Uberon needs to be clearer in the layered composition of some structures - the ducts have mucosal and muscle layers as well as epithelium
