Summary:
Unwind segues called from the master view controller of the standard split view controller arrangement cannot unwind past their own master view controller, even when the same unwind works from a detail VC in the same split.

Steps to Reproduce:
Run the attached UnwindBuglet project. This consists of:
1. A FirstViewController scene with a "login" button, and an unwindToFirstViewController() method. When tapped, the login button does a modal segue to…
2. A UISplitViewController, consisting of:
3. A UINavigationController whose root is a MasterViewController, which is just a UITableViewController subclass. This has two cells, which will be explained in a moment
4. A plain UIViewController for the detail VC

The table in 3 has two cells: one is wired to an exit segue to go back to unwindToFirstViewController(), and the other goes to the usual selection handling, which calls performSegueWithIdentifier("manualUnwindToFirstViewController"), which is a manual exit segue.

The VC in 4 has a single button to perform an exit segue to unwindToFirstViewController()

Expected Results:
All exit segues should unwind back to the first view controller

Actual Results:
Only the button in the detail VC can unwind to the first VC. The exit segues in cells of the master VC do nothing.
