Now permissions are updated as follows:
1. do graph modifications ignoring permissions
2. do permission update
(of course, we rollback [1] if [2] fails)
So, on stage [2] we can't say which users are "old" and which are
"new" and exist only since [1]. And current error message is a bit
outdated. Let's improve it, to make everything clean.
While being here, add also a comment and some good assertions.
iotests 283, 307, qsd-jobs outputs are updated.
