"Add argument name" requires you to be on exactly the argument

[davkean]

1. CTRL+. at $

using System;

class Program
{
    static void Main(string[] args)
    {
        Console.WriteLine(args$);        
    }
}

Expected: To be offered to "Add argument name"
Actual: Not offered to "Add argument name"

Note, for highlighting usage and goto definition purposes that character position is considered part of the argument.

@alrz want to take a look? @CyrusNajmabadi do you know if we have better for refactorings to use here?

We have a helper called "GetTouchingWordAsync" which may be helpful here. But, since the last token may not be a keyword/idntifier, we probably just need to check if the current token is ) or ,, and we're at the start of it, then just move back one token.
