Update -internal.js

[vivekkodira1]

Adds logic to log the error in the console. Doing this since to ensure better logging from the method for developers who have not used the ".catch()" notation in the calling methods.

This will result in false positives, the correct solution would be to schedule the error at the end of the current turn, and if the promise isn't then handled log.

I did this already in RSVP:

• https://github.com/tildeio/rsvp.js/blob/master/lib/rsvp/-internal.js#L69
• https://github.com/tildeio/rsvp.js/blob/master/lib/rsvp/-internal.js#L113-L115
• https://github.com/tildeio/rsvp.js/blob/master/lib/rsvp/-internal.js#L146

Fully intend to eventually port it here, just haven't had a chance. If you hare motivated/interested it would be quite helpful
