Fix formatting of comment in paren of call expression in arrow expression

[jackyho112]

Fixes #2853 (comment).

Fix an edge case where a comment inside the parentheses of a call expression of an arrow function expression with no bracket would have the arrow function expression, instead of the call expression, as the enclosing node. Therefore, when checking for whether there is an argument, we might get the wrong result.

For example,

const API = {
  loader: () => import('./test' /* webpackChunkName: "test" */),
};

would get formatted to

const API = {
  loader: (/* webpackChunkName: "test" */) => import("./test")
};

before this fix. But with this fix, the comment won't get moved.

Let me know if there is any improvement I could make. 😄
