redundant Promise.then usage #14

https://git.coolaj86.com/coolaj86/greenlock.js/src/branch/master/lib/core.js#L439

Doing

promise.then(function (results) {
  return results;
})

Is redundant, without that clause the promise will already resolve to results.

Correct, this is safe to remove.

It's probably leftover from some debugging or a transformation of data, or a control flow branch that was removed.

I'll leave this open to remind me to take care of that.

AJ - do you have any objections to adding jest in for unit testing? I know this is a trivial change but that makes it useful for proving test automation.

Your hand rolled test code keeps things simple but I appreciate the extra info that using a framework provides.

(btw - what the target minimum node level? I am working with 8 but tend to babel compile from 7+.)

Happy to create a pull request for this one, with or without jest

No objections.

Thank you, btw.

Sorry about delay - I got stuck trying to wire a test around it. Not sure how to best test? Do you generally point it at the sandbox on an internet IP for testing?

@chanoch Yes. I create a temporary digital ocean vps and point four test domains at it and run through a few different scenarios.

Then I deploy it to git.coolaj86.com and a possibly a few other sites to see if it works in my existing setups as well.
