cubicweb-forge #1368889 change a ticket's project gives strange result if ticket is attached to a version [open]

ticket A is attached to version N of projet P1. I need to reassign A to project P2.

I use the edition view, and change the project.

The primary view of A still mentions P1 in the breadcrumbs, because this goes through the Version relation.

changing the projet must reset the version of the ticket.
