    Fix GncPopupEntry missing property error
    
    There was error in the trace file for GncPopupEntry of the format...
    Object class GncPopupEntry doesn't implement property 'editing-canceled'

    Bug 797492 - Lock up on 'Find Account'
    
    If you list accounts with the "find accounts" dialogue, then delete an
    account it has found (e.g. jump & delete), then return to the dialogue,
    the dialogue doesn't refresh when the window regains the focus, so you
    can accidentally jump to an account you have recently deleted which
    will lock up Gnucash.
    
    Fix this by listening to account events and then refresh the list.
