The sync-test zone is used in e.g. `describe` to raise an error when there is asynchronous code scheduled in describe blocks. This commit includes the zone name in such thrown errors to allow for us to include the jasmine describe name in the error. This will be wired up in the jasmine zonejs patches separately.
