Handle pubspec.yaml files with no dependencies (#17195)
Currently, `flutter update-packages --force-upgrade` will
crash if it encounters a pubspec.yaml file with no dependencies
(either regular or dev). The assumption that we'd never see
such pubspec files is no longer valid, as we have such a file
in one of our tests.
