[treeview] ensure items are ordered according to their dc_title, we can't rely on an ordered rset
* is_last has to be computed on the caller now, not possible in the callee
* rely on b3f61c38526b to use entity.view() with vid in *view*'s arguments
# some entities have been added before schema entities, fix the 'is' and
# 'is_instance_of' relations
for rtype in ('is', 'is_instance_of'):
