Look in the tests root dir for jira.cfg and not only in the current dir

[Horstage]

My tests are ordered like this

test
│   jira.cfg
│   conftest.py
│   ...
│
└───category1
│   │   conftest.py
│   │   ...
│
│   
└───category2
│   │   conftest.py
│   │   ...
│

When starting pytest within category1 the higher-level conftest.py is included by pytest, such that test is the actual root dir of the tests. But the jira.cfg in the root dir is ignored. This PR aims to change that!

This PR is quite conservative, I'd rather move the config to the pytest.ini, but I'll do another PR for that ;-)

I could resolve that issue but this would go against best practices, so I won't unless you specifically ask me to.

Now tests looks much better!

I am good with this change, @petr-balogh could you please take a look at this change?

[lukas-bednar]

Thank you!

I was hoping for a rather quick update of the pypi package ;-)
