Navigating back from comment view causes front-page reload

[mdaniel]

To reproduce this visually, one will need to wait until "rush hour" on HN, so there is a greater than average chance of articles repositioning themselves on refresh. Or you can use a really slow connection, since the refresh is not instantaneous.

1. Launch the app
2. Click on an article to navigate to the comments for it
3. Press the back button
4. Observe that HackerNews reloads the front page list even though it was just loaded a few seconds ago

My concern with this bug is less about the delay caused by the reload and more about losing my place while I was reading down the list. Since the items are going to be reordered on refresh (usually), then I have to keep in my head which ones I've seen already.
