With two incoming file transfers using the same file name, and auto-accept on,
Konvi will pop up a dialog asking what to do about the dupe. Pressing Cancel in
this dialog crashes the app.

SVN commit 1036287 by buschinski:

- Fix dcc crash for getting a tranfser twice(same name) and cancel one, KIO
reuses TransferJobs, so we can't kill the job, just hold it and let KIO decide
when it is really unused
BUG:210607
- Fix transferpanel crash for the cases:
    + cleanCompleted and never had a transfer in the panel
    + multi-selected transfers, clear, not all transfers were cleared, but
panel transfer got deleted



 M  +3 -3      transferpanel.cpp  
 M  +6 -3      transferrecv.cpp
