The limit plugin called build_limit() with the host-group and
project-group managers swapped, so a limit's hosts: members were looked up
among the project groups (a host-group name became a literal host name and
the limit never applied) and its projects: members among the host groups.
Pass them in the order build_limit() declares.
New test test_limit_scopes_resolve_against_own_group_kind; the test's
main() now initializes the interned-string table that group names need.
