The test was trying to wait for the replica to start loading the rdb from the master before it kills the master, but it was actually waiting for ROLE to be in "sync" mode, which corresponds to REPL_STATE_TRANSFER that starts before the actual loading starts. now instead it waits for the loading flag to be set. Besides, the test was dependent on the previous configuration of the servers, relying on the fact the replica is configured to persist (either RDB of AOF), now it is set explicitly.
