Passing `arg-*` to the `await` tag does not inject arguments into the target method.

Bug Report

Marko Version: 4.7.0

Details

Passing arg-* to the await tag does not inject arguments into the target method.

Expected Behavior

Arguments passed via await tag attributes are injected into the target method.

Actual Behavior

Arguments passed via await tag attributes are not injected into the target method.

Possible Fix

Within await-tag.js, using the same call on the provider rather than using a conditional seems to fix the issue but I'm sure this statement existed to resolve another problem so I'm not confident this will be the fix.

// marko/src/taglibs/async/await-tag.js
var value = (provider.length === 1) ?
    // one argument so only provide callback to function call

    // [FIX] (`args` added)
    provider.call(thisObj, args, callback) :

    // two arguments so provide args and callback to function call
    provider.call(thisObj, args, callback);

Your Environment

Chrome 62.0.3202.94 (Official Build) (64-bit)
Mac OSX 10.1.6

Steps to Reproduce

Create a new component with Try Online or local dev environment that depends on await:


$ input = { duration: 5000, error: false };
$ function wasteTime({ duration, error }) {
console.log('arg error:', error);
console.log('arg duration:', duration);  
if (error) return Promise.reject('failed');
return new Promise((resolve) => setTimeout(resolve, duration * 1000)).then(() => 'done!');
}

<await(result from wasteTime) arg-duration=input.duration arg-error=input.error>

[ spinner ]

Request timed out

Something bad happened!

I loaded after ${input.duration} seconds with: ${result}


2. Check the console, both arguments (`duration`, `error`) are undefined.
3. If you're running this locally, modify the line identified under "Possible Fix" and re-run the same code successfully.
