marking a todo as completed from the search results list causes todos to use old table cell style

[mikemccracken]

To reproduce: start from main view, unfiltered (not sure if that matters)
some of this is probably unrelated to the bug, but just for completeness, here's what I did:
This is on iOS 7.1.

1. add a todo, just the string 'fffffffff'
2. drag down to reveal search field
3. type 'ffff' to show the new todo
4. swipe left to show 'complete' button. press it
5. hit 'cancel' to undo the search
   6 note that all the todos now use a very old style - where there's a red circular delete button on the left.
