cubicweb-trackervcs #4849349 in forge, ticket created upon validation refusal should not carry patches from the former ticket [validation pending]

Currently, upon validation refusal a new ticket is created and closed_by and patch_ticket relations are copied. IMHO, copying these relations does not make sense. The issue appears in forge, but should be fixed in trackervcs because the latter defines aforementioned relations whereas the former does not known about them.
