[v8] Options decorator without arguments

[Mikilll94]

In v7 I was able to use @Component decorator like this:

@Component
export default class App extends Vue {

}

However in v8 when I use a decorator like this:

@Options
export default class App extends Vue {

}

I receive the following error:

Repro project: class-component-test.zip

Intentional. If you don't need arguments, you should just remove @Options.
