Adding support for calling function with `this` context (object/class methods)

Consider the class

export default class API {
  fetch() {
    console.log(this);
  }
}

With backend = new API(), the call yield call(backend.fetch) logs undefined, whereas yield backend.fetch() logs the correct this.

Edit: yield call(backend.fetch.bind(backend)) works fine, too. So feel free to close this if you don’t consider this an bug.

using arrow functions instead of methods also does the trick for example: convert this code

export default class API {
  fetch() {
    console.log(this);
  }
}

to this

export default class API {
  fetch = () => {
    console.log(this);
  }
}

In addition: Binding the class Object itself with yield call(MyClass.myMethod.bind(MyClass)) seems to preserve the this context as well, even though apply should be the solution of choice.
