Code assit: remove extra argument(s)

[Kmeakin]

fn f1() {}

fn f2() {
    f1("hello");
    f1("hello", "rust");
}

It would be nice to save some typing if rust-analyzer could provide a fixit to delete extra arguments when a function is called with too many arguments (ie Ctrl+. on "hello" or "rust" in the code above)
