No, root has no password anymore. If you want one:
xc-attach -n foo -- passwd

The changelog/NEWS might add a blurb that there is no more default
password. But other than that I only see the initial bug with your old
container, but that's wiped now :( - can you provide input how it was
created? vanilla jessie lxc (1.0.x), lxc-create -t debian, upgrade to
lxc 2.0?
