[ios] Link posts no longer show the URL

Posts no longer display the link that they go to in the iOS app (across all subreddits, not just /r/news). This makes it much more difficult to know which articles I want to read and which ones I don’t.

But more than that, this is potentially dangerous- there’s no way to see whether a post’s link is malicious or not without clicking it.

For as long as I can remember, the app would show where the link actually goes in the upper right corner.
