Follow new role scheme in Prosody

Prosody changed its role scheme to only support a single primary role
for each user. In addition, the names of the built-in roles have been
changed. We thus follow those changes to be compatible with the most
recent trunk.

One open question is whether we should switch admin -> operator here,
too (operator being a server-wide admin), but so far there's no need
to.
