don't show incorrect 'How odd' errror in no-download mode

Showing messages related to downloading in a mode which can't download
is pretty pointless, so instead of trying harder to make it so that
these messages do not trigger just skip them entirely.

That the message triggered here is an artifact of the implementation in
which the download items are finished, while the code expects them to be
still pending – even the in a previous run completely downloaded files.
