login screen shows up on iphone even when logged in

[Janne Hellsten]

Steps to repro:

1. goto the site (having previously logged in)
2. you will see the login screen for 0.5-1.0 seconds, then you're taken to the actual app

Reason is probably that appContext is null after loading index.html, which means any attempts to load the home screen will first render an empty login instead. After that reloadHome re-renders the main screen.
