    Revert "IMAPx: Correct ref/unref imbalance on a GConverter in/out base streams"
    
    Even it did not crash when testing, it did crash later. The in/out
    streams here are not new streams, they are owned by other object.
    
    This reverts commit b6866f7cebe96c66ad13771f899f953ff01c4d4c.
