    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 5e6569908638e9523d495d78dc3aa24ee96d5cad.
