jumbo flag in chunk can be cleared when the shard that owns it donates a chunk

    • Fully Compatible
    • ALL
    • v4.2, v4.0, v3.6
    • Sharding 2019-07-01

      During the commit phase of the migration, the moveChunk command will set the chunk being migrated with a new major version and selects a random chunk of the current shard to have the same major version. This is done using replacement update so if a chunk that gets selected is a jumbo chunk, the flag will get cleared inadvertently.

      Also uncomment this line in test after fixing:
