Fix load_from_json

[CasperWA]

This function did not work properly.

Add test file for config.py, for now only with a simple test to run load_from_json().

Feel free to add more tests to test_config.py either in this PR or later.

Thanks for this @CasperWA!

I've just added the same test on our default config.ini, guess its a bit redundant as its being tested indirectly everywhere else, but oh well!

I'll approve this and you can merge, unless you see any issues with my changes.

Don't see any problems, only - why not use the actual config.ini file for these tests? Then we'll also know if we do something wrong with that one :)

Could do, I just figured having a separate test file might be helpful if we make any changes to the default. I'll leave it up to you!
