[uicfg] fix autoform_section rtags initialization 1. when a relation is marked as inlined in the 'main' form type, we want its opposite (eg when one the other side of the relation) to be marked as hidden in the 'inlined' form type 2. when no section is specified for the 'inlined' form type, use the same as in the 'main' form type to do this properly, we need two initialization stages. The first one to handle 1., the second to handle what was done before and 2. We can't do this in a single stage because we've to know the bare value of the "opposite" tag.

# some entities have been added before schema entities, fix the 'is' and
# 'is_instance_of' relations
