Correct LUCI config errors

Config revision 5b8bdcf was rejected because:
* WARNING: commit-queue.cfg: in "commit-queue.cfg" (config_group #1): please, specify `name` for monitoring and analytics
* ERROR: refs.cfg: refs.cfg is not used since 2019 and must be deleted

This change addresses those errors and warnings.
