Going through DownloadActivity breaks downloading if multiple downloads are started at the same time

To replicate, start multiple downloads by calling DownloadActivity multiple times. Chances are only the first one will stick.

If DownloadActivity is bypassed and the code is inlined at the call site, it works correctly, by downloading all the games.

Context, we use it embedded in an app, and we might have up to 3 love games that we need to download, and we will try to download one after the other in rapid succession.
