Unstable comment of last argument of a method

[vjeux]

#856 fixed it for functions and types but not for methods.

class X {
  f(
    currentRequest: {a: number},
    // TODO this is a very very very very long comment that makes it go > 80 columns
  ) {}
}

outputs

class X {
  f(
    currentRequest: { a: number }
  ) // TODO this is a very very very very long comment that makes it go > 80 columns
  {
  }
}

which ouputs

class X {
  f(
    currentRequest: { a: number } // TODO this is a very very very very long comment that makes it go > 80 columns
  ) {}
}
