clang-format: [JS] Understand object literals with only methods.

Before:
  let theObject = {someMethodName() {
    doTheThing();
    doTheOtherThing();
  },
                   someOtherMethodName() {
                     doSomething();
                     doSomethingElse();
                   }};

After:
  let theObject = {
    someMethodName() {
      doTheThing();
      doTheOtherThing();
    },
    someOtherMethodName() {
      doSomething();
      doSomethingElse();
    }
  };
