This is to implement a card for the feed that shows a completely random article for the user to read.
When the random article is downloaded
Then I should see a random article in a preview card.
When I tap the "random" button
Then I should see a new random article
When I am presented with a random article
Then it should not be a disambiguation page
And it should be in the main namespace (i.e. not a Category:, File:, Wikipedia:, Template:, etc.)
