Label-studio: Bug when starting release branch 0.7.3

I am on Windows with Python 3.7.
I did pip install git+https://github.com/heartexlabs/label-studio.git@release/0.7.3 but got the error below

What host name and port do you use to start LS?

[makseq]

Please, check my latest commit on release/0.7.3 branch (Fix with sockeraddr on windows).

@RasmusEdvardsen have you the same issue with socket bind?

[RasmusEdvardsen]

@makseq Yes, I do

label-studio version:

@makseq
The issue is in app.run(host=host,...) where host now has the protocol prepended to the address (http://localhost), whereas it was just the path previously (localhost)

Also, this is a problem, when the config file is generated by the init script from the cli.
0.7.2:
"host": "0.0.0.0",

0.7.3-rc:
"host": "http://0.0.0.0",

[makseq]

@RasmusEdvardsen check the latest commit now, please.
If you use the old project, be sure there is "host": "localhost" in project/config.json, without "http://"

[RasmusEdvardsen]

@makseq perfect!
