* src/modest-ui-actions.c:
        * Removed annoying warning for check retrieval in message open
          handler. THis was appearing everytime we cancelled a
          message retrieval.
* src/modest-mail-operation.c:
        * Now we notify the end of the mail operation before
          unreferencing. This prevents a crash.
        * Now we do a tny_account_cancel in status handler when we
          get a cancel status. This way we properly cancel the
          message download (and then we can try again to open the
          message as expected (fixes NB#62444).
