SA1107 Fix All in Solution appears to throw an exception

[sharwell]

I'm working with Newtonsoft.Json.Portable.sln from the recently added churn tests, and ran StyleCopTester with /id:SA1107 /fixall. I haven't yet tracked down the cause.

The fix 'SA1107CodeFixProvider' threw an exception after 33ms:
System.NullReferenceException: Object reference not set to an instance of an object.
