Ancestors: Tests-ar.71

The previous fix for MCChangeNotificationTest was incomplete and based on flawed analysis. This one should do better.

- 	"FIXME: Unregister Monticellomocks if it got created implicitly.
- 	This avoids a nasty failure of MCChangeNotificationTest due to
- 	some inconsistency about whether package names are case sensitive
- 	or not. They're treated as case insensitive in some name lookups but not
- 	in others; most importantly PackageOrganizer default treats package
- 	names as being case sensitive. The package created here is Monticellomocks
- 	(lower case mocks) and an instance of PackageInfo; the package expected
- 	in MCChangeNotificationTest is MonticelloMocks and an instance of
- 	MCMockPackageInfo. Since *that* lookup is case insensitive it can
- 	find Monticellomocks instead of MonticelloMocks and fail."
