py-test-xdist: updated to 1.30.0

pytest-xdist 1.30.0:

Features
* Initialization between workers and master nodes is now more consistent, which \ 
fixes a number of long-standing issues related to startup with the -c option.

Issues:
* Poor interaction between -n# and -c X.cfg
* pytest-xdist is not reporting the same nodeid as pytest does
This however only works with pytest 5.1 or later, as it required changes in \ 
pytest itself.
