Annotated type vars have incorrect output type name

[niloc132]

Annotated type variables can be written out to typescript with an invalid type name. This was noticed on a properties, but it could be wrong elsewhere.

Example that fails:

@TsInterface
@TsName(namespace = "myapp")
public interface MyOptional<T> {
  @JsProperty
  @JsNullable
  T getValue();
}

As @JsNullable is a TYPE_USE annotation, it apparently is attached to the T instead of the method, and accidentally is toString()'d when the type is written out in TS.

Expected output:

export namespace myapp {
        interface MyOptional<T> {
                get value(): null|T;
                // or this might also be valid, still not sure why it sometimes changes
                //readonly value?: null | T;
        }
}

Actual output:

export namespace myapp {
	export interface JsOptional<T> {
		readonly value?:null|@jsinterop.annotations.JsNullable T;
	}
}
