[Bug] Admin taxon update: Cannot set child as parent to node

[igormukhingmailcom]

Sylius version affected: master/>1.7.6

• We have Cannot set child as parent to node: ... exception if we're trying to set current taxon as parent on taxon update.

Possible solution:

• Create special endpoint like /admin/ajax/taxons/<ID>/parent/search (new route like sylius_admin_ajax_taxon_parent_by_name_phrase), which will exclude current and child taxons from search
• Add validator which will check submitted parent taxon is not current one and not one of childs

Validator seems like a simpler option to me.
