Imported Closed Issues Aren't Closed In GitHub

[envisionnw]

Likely related to #35 , however while transferred issues are identified as [CLOSED] they are not "closed" in GitHub and appear when filtering "issues:open" and vice versa for open issues. This may be a coincidence but the # of open issues imported to destination = # of closed issues in source (& vice versa).

Milestones completed in source were incomplete in destination.

Milestone issues are tagged as for a specific milestone, but looking via the milestone shows no issues.

Started out with 66 issues with milestones & comments in various states (closed/open) and ran

>>> import runpy
>>> import sys
>>> sys.argv = ["","-i","29","30","31","32","33","34","35","36","37","38","39","40","41","42","43","44","45","46","47","48","49","50","51","52","53","54","55","56","57","58","59","60","61","62","63","64","65","66","67","68","69","70","71","72","73","74","75","76","77","78","79","80","81","82","83","84","85","86","87","88","89","90","91","92","93","94"]

to start.
First issues (30?) were copied over with the following traceback to request.py [file specific tracebacks removed]:

   raise HTTPError(req.full_url, code, msg, hdrs, fp)
urllib.error.HTTPError: HTTP Error 403: Forbidden

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

Double check that your username and password are correct, and that you have permission to read from or write to the specified repositories.

So I attempted to chunk the remaining issues, yielding portions of success (copied issues/comments) but unfortunately not everything migrating as expected.

Great script with some tweaks it will be even better. Thanks!
