bugfix: native component branch forks that clash are MERGED rather than overwritten. Avoids race condition where (1) branch x ends and submits a solution, (2) branch y is created, has same predicate as x and overwrites it, but has a subset of its messages, (3) round ends in success but branch x is gone, so no suitable native branch is found
