Quick media list filter does not work on the top of TuneIn service

[mkulesh]

For Premium version and Denon only. For Onkyo works as desired.

The problem is that the filter functionality is blocked by downloadFinished check in the MediaListView:

if (!applyFilter && ms.downloadCtrl.downloadFinished)
{
  _processLayerInfo(ms, dataItems);
}

From any reason, the total number of items on the of TuneIn service is zero and the check

bool get downloadFinished
=> _total == _downloaded;

in MediaDownloadCtrl fails.

How to reproduce

• Connect to Denon
• Select HEOS input channel
• Open TuneIn service
• Press "Quick Filter" button
• Try to enter some symbols
  Expected behavior: input is possible, filter works
  Observed behavior: input is not possible, no filter applied
