                     * This is an edge case that may come up and which we must handle properly. Relationship groups are
                     * not managed by the tx state, since they are created as side effects rather than through
                     * direct calls. However, they differ from say, dynamic records, in that their management can happen
                     * through separate code paths. What we are interested in here is the following scenario.
                     * 0. A node has one less relationship that is required to transition to dense node. The relationships
                     *    it has belong to at least two different types
                     * 1. In the same tx, a relationship is added making the node dense and all the relationships of a type
                     *    are removed from that node. Regardless of the order these operations happen, the creation of the
                     *    relationship (and the transition of the node to dense) will happen first.
                     * 2. A relationship group will be created because of the transition to dense and then deleted because
                     *    all the relationships it would hold are no longer there. This results in a relationship group
                     *    command that appears in the tx as not in use. Depending on the final order of operations, this
                     *    can end up using an id that is higher than the highest id seen so far. This may not be a problem
                     *    for a single instance, but it can result in errors in cases where transactions are applied
                     *    externally, such as backup or HA.
                     *
                     * The way we deal with this issue here is by not issuing a command for that offending record. This is
                     * safe, since the record is not in use and never was, so the high id is not necessary to change and
                     * the store remains consistent.
