Dealing with extra choices when downloading from EGS

I wanted to install Fallout 3: GOTY via EGS. Once I press 'install' the installation does not start, the steam entry gets made, but the game does never install.

Once I tried to do the installation via commandline I think why it is behaving this way. Legendary will ask for which language to download, which I think is causing the issue.

```
[gamer@chimeraos ~]$ legendary install adeae8bbfc94427db57c7dfecce3f1d4

You are about to install Fallout 3: Game of the Year Edition, this application supports selective downloads.
The following optional packs are available (tag - name):
* de - (Additional Languages) Deutsch

* it - (Additional Languages) italiano
Please enter tags of pack(s) to install (space/comma-separated, e.g. "de, es")
Leave blank to use defaults (only required data will be downloaded).

Other games I have do not do this.

Start at the EGS installation entry point that invokes the `legendary install` command and trace how its interactive optional-pack prompt is handled. Reproduce the Fallout 3: Game of the Year Edition installation, then verify that the UI completes the installation without waiting for language-pack input.
