Redundant CL annotations remove bug

[hkir-dev]

There seems to be a bug in redundant CL annotation removal.

Example dataset:

• https://cellxgene.cziscience.com/collections/d17249d2-0e6e-4500-abb8-e6c93fa1ac6f
• Dissection: Middle temporal gyrus (MTG)
• labelsets:
  • CrossArea_cluster
  • CrossArea_subclass
  • Class

Original data:

cell_label	parent_cell_set_name	cell_ontology_term_id
Vip_2	Vip	CL:4023016
Vip	inhibitory	CL:4023016
inhibitory	None	CL:4023011

When AnnData to CAS run, only inhibitory has CL annotations, while Vip should have an annotation as well.

cell_label	parent_cell_set_name	cell_ontology_term_id
Vip_2	Vip	None
Vip	inhibitory	None
inhibitory	None	CL:4023011
