Trying to install a DLC without the main game installed fails with no error and success message

[arielj]

Describe the bug

When trying to install a DLC for a game, Heroic shows the install dialog, it allows the user to continue with the installation, starts showing some progress, and then finishes with an Installation finished notification but the game is not installed and it's not displayed as installed in the list of games.

Steps to reproduce

Try to install a DLC when the main game is not installed

An example to try is Alien: Isolation - Last Survivor, the DLC for Alien: Isolation that Epic gave for free at some point.

Expected behavior

Heroic should warn the user that the game they are trying to install requires another game to be installed first if the game is not installed.

It shouldn't let the user continue without installing the original game or, if we let the user continue, we should show a proper error message explaining that it failed and why.
