Title: Fixed crash for empty repositories

Empty repositories will have a `null` in their `pushed_at` date. This
would cause the app to crash when comparing the repositories by that date.

This patch compares the dates to `NSNull` first and then to each other. Additionally this is now done in a named block instead of four unnamed ones.

This fixes the problem I reported in #13.
