Using "null" in mobile_builds should not default to element app

[estellecomment]

Steps to reproduce

1. Where are you starting? What can you see?
   Configure "mobile_builds" as indicated in config.md, to have no fdroid app.

    "mobile_builds": {
        "ios": "my ios url",
        "android": "my android url",
        "fdroid": null
    },

The documentation says :
"When explicitly null, the app will assume the iOS app cannot be downloaded. When not provided, the default Element app will be assumed available."

2. What do you click?
   Create a new account. Log in. On first connection, you get UserOnboardingTasks in the main panel.
   Click "Download apps" to get AppDownloadDialog.

Outcome

What did you expect?

No link for fdroid app, as indicated in config.md

What happened instead?

Link to fdroid app for element's android app.
