Http server errors out.

I had the supervisor server stood up, and for some reason it fails to extract the server name / http host value from the request headers. This used to work but after a fresh pip install of supervisor it started to give me this error.

ERRO :Server Error: <class 'TypeError'>, unsupported operand type(s) for +: 'NoneType' and 'str': file: /usr/local/src/supervisor/supervisor/http.py line: 328

What version of Supervisor did you install with pip?

Error message from above:

ERRO :Server Error: <class 'TypeError'>, unsupported operand type(s) for +: 
'NoneType' and 'str': file: /usr/local/src/supervisor/supervisor/http.py line: 328

Line 328 in Supervisor 4.0.4:

supervisor/supervisor/http.py

Line 328 in 44eefd5

if server_url[-1:]=='/':

There is no + on line 328 in Supervisor 4.0.4 (the latest release version) so you must have installed some other version.

my line in pip requirements file was
-e git+https://github.com/Supervisor/supervisor@master#egg=supervisor

I will use the pip install supervisor instead, Thanks.
