cloning 926250, reassign -1 to python3-jsondiff ..., found -1 in 1.1.1-3, tagging -1

[Axel Beckert]

clone 926250 -1
reassign -1 python3-jsondiff 
# The pending solution for #926250 in python3-jsonpatch is using update-alternatives, so should it be done here, too
retitle -1 python3-jsondiff: File conflict between python3-jsondiff and python3-jsonpatch: /usr/bin/jsondiff should be managed via update-alternatives
found -1 1.1.1-3
tags -1 - pending
thanks
