/**
* Reset the ids caches completely

* with the backup_ids table must cause the backup_ids caches to be
* invalidated by calling this method. See MDL-33630.
*
* Note that right now, the only operation of that type is the recreation
* (drop & restore) of the table that may happen once the prechecks have ended. All
* the rest of operations are always routed via {@link set_backup_ids_record()}, 1 by 1,
* keeping the caches on sync.
*
* @todo MDL-25290 static should be replaced with MUC code.
