refactor(dialog): remove styles for deprecated md-actions class

- remove code and tests for warning about deprecated `md-actions` class
- remove unused injections in tests
- fix `md-fab-speed-dial` demo that used `md-actions` class

BREAKING CHANGE: Removed support for the deprecated `class="md-actions"` inside of an `md-dialog` template. This was deprecated in favor of using the `<md-dialog-actions>` element.
