WebUI: remove deleted torrents even if they are currently filtered out

Remove the torrent row regardless of it being visible.

I've also removed the return value because:
* it doesn't appear to be used by any caller;
* other functions (e.g. updateRowData) do not return any value;
* it's not clear whether true refers to the torrent being removed from the list of all torrents or just the visible ones.

Closes #21070.
PR #21071.
