Resolve and Inject value parameter needs to be optional for static class methods

[linnenschmidt]

In Typescript for static class methods, there is an error with the value property of the defineProperty descriptor.

@Component({
  selector: 'my-component',
  template: 'template'
})
@Inject('resolveSomething', MyService)
export class MyComponent {

  @Resolve()
  @Inject(MyService)
  static resolveSomething(MyService: MyService) {
    return MyService.getSomething();
  }
}

Argument of type 'TypedPropertyDescriptor<(MyService: MyService) => any>' is not assignable to parameter of type '{ value: any; }'.
Property 'value' is optional in type 'TypedPropertyDescriptor<(MyService: MyService) => any>' but required in type '{ value: any; }'.

Here ist the optional value of the TypedPropertyDescriptor: https://github.com/Microsoft/TypeScript/blob/727b9/src/lib/core.d.ts#L1245
