Node conflating cell and anatomical feature

[cbizon]

Every cell is also an anatomical feature. But also, since cell is a cellular component, every cell should have as labels named_thing, cell, anatomical_entity, and cellular_component. We have one node that does not have cellular component. Its equivalent identifiers are UBERON:0022285,CL:1001436.

This is conflating two distinct concepts: an anatomical structure, and the cell type that ennervates that structure. I think it's driven by the xref from uberon to cl, and should be fixed with the upcoming refactoring of synonymization.
