HTTP Basic Auth - sending username but no password triggers exception

[philipithomas]

Reported on our repo here: Staffjoy/suite#3

We send an API key as an HTTP basic username without a password, e.g. curl --user API_KEY: http://app.local. This appears to throw the following error on python 2.7 with unirest 1.1.7:

Traceback (most recent call last):
  File "/opt/python/2.7.12/lib/python2.7/threading.py", line 801, in __bootstrap_inner

TypeError: unsupported operand type(s) for +: 'NoneType' and 'str'
