pass error when rejecting promise

Now error can be used in catch block that handles the error

@redpandatronicsuk thanks for the PR. I see you are passing the error in the reject. If you take a look on the line before reject, you will see that I am using a function called handleError. This function actually extracts all the useful part of the error, format it, and then show it to the user. If we pass the error in reject as well, it is going to show a duplicate error if the user logs it in the catch. One formatted and the other non-formatted.

But I think your approach is better and is more general. Would you mind editing the PR and remove the handleError part as well as removing the dependency?
