unusedArguments does not work with functions calling functions with the same labels

[reika727]

I have a code like this:

func f(foo _: Int) {}

func g(foo: Int) {
    f(foo: 42)
}

This code does not change after being formatted. However, the argument foo is not used inside the function g, so it should be func g(foo _: Int) (since the unusedArguments option is enabled by default.)

If you comment out the call of f inside g, the code will be formatted properly.

// BEFORE FORMATTED
func f(foo _: Int) {}

func g(foo: Int) {
    // f(foo: 42)
}

// AFTER FORMATTED
func f(foo _: Int) {}

func g(foo _: Int) {
    // f(foo: 42)
}

So maybe this strange behavior comes from f and g having the same argument label foo?
