Unfinished project download may leave incomplete directory

[wonder-sk]

Download of a project may get interrupted, even without getting a signal about the failure of a request.

This will leave a half-populated directory and may cause further trouble later.

We should have a mechanism that will ensure that half-downloaded projects are never shown in the list - and any half-downloaded project data get pruned. For example, we could download to a dir with a special prefix, and directories with such prefix would be never shown (+would get deleted when Input starts)

TODO: find out when exactly this happens (app gets to background? app is forcefully quit?)

Upon investigating I found out that failed download (only when application quits) keeps the directory. When opening app again it lists the project with error. Next time trying to download creates new directory with 0,1,2... at the end based on how many times it failed already.
