Gracefully cancel cell reordering when application will resign active notification sent

The example with the card images doesn't reflect this bug (because of the ample spacing between the cells and the status bar), but if your cells are flush against to status bar (in iPhone, at least), when the user long presses on a cell at the top, the Notification Center drawer is pulled down and the cell gets stuck in the long press state.

Here's what I mean by it getting stuck in the long press state:

Pay attention to the "Groceries" cell.  My finger is no longer on the screen, but the rasterized cell is stuck in place.  This totally breaks the scroll view.
