Reconfiguring replica sets hang with ephemeralForTest

      This test hangs when using Biggie storage engine: jstests/replsets/awaitable_ismaster_on_nodes_with_invalid_configs.js

      The new config is not propagated correctly and nodes wait indefinitely to find themselves in the config.

      The test triggers these warnings in the log:
      "** WARNING: This replica set node is running without journaling enabled but the "
      "** writeConcernMajorityJournalDefault option to the replica set config "
      "** is set to true. The writeConcernMajorityJournalDefault "
      "** option to the replica set config must be set to false "
      "** or w:majority write concerns will never complete."
      "** In addition, this node's memory consumption may increase until all"
      "** available free RAM is exhausted."
      ""
      ""
      "** WARNING: This replica set node is using in-memory (ephemeral) storage with the"
      "** writeConcernMajorityJournalDefault option to the replica set config "
      "** set to true. The writeConcernMajorityJournalDefault option to the "
      "** replica set config must be set to false "
      "** or w:majority write concerns will never complete."
      "** In addition, this node's memory consumption may increase until all"
      "** available free RAM is exhausted."
      ""

      writeConcernMajorityJournalDefault is supposed to be set to off:

      But there seem to be paths where this does not happen
