Bad instrumentation of constructor super-call with spread operator

[mhelvens]

Have a look at this minimal ES6 example code:

export default class MyError extends Error {
    constructor(...args) {
        super(...args);
    }
}

After Wallaby instruments this code, it looks like this:

$_$wp(1);
export default class MyError extends Error {
    constructor(...args) {
        super(($_$wf(1), $_$w(1, 0), ...args));
    }
}

That super line now has a syntax error, because the spread operator ... is not expected in a comma expression. You probably want to check for this and output something like this instead:

super(...($_$wf(1), $_$w(1, 0), args));

I'd create a pull request, but I'm not sure where you're hosting your code.

Awesome find, thanks! Fixed like you have suggested.
