    Reinstate leak fix for GSimpleAsyncResult objects
    
    Now that the stray connection unref should be fixed, we can reinstate
    the fix for the leaked GSimpleAsyncResults. A slightly improved version
    over commit 1ac06aa5, this one prevents a possible use-after-free
    because the connection is pinned by the result, so we must do it *in*
    ews_active_job_done() after we've done everything we want to with
    enode->cnc.
