Populate components list from AppRegistry if app.json is empty/missing

[tido64]

If the list of components in the manifest (app.json) is empty or missing, we should be able to retrieve the list of registered components from AppRegistry.

Remaining work:

• Android (feat(android): populate home screen with AppRegistry entries #1127)
• iOS (feat: populate home screen with AppRegistry entries #482)
• macOS (feat: populate home screen with AppRegistry entries #482)
• Windows (feat: populate home screen with AppRegistry entries #482)

Reopened to keep track on the missing Android implementation.
