py-test-xdist: updated to 1.26.0

pytest-xdist 1.26.0:

Features
- The current directory is no longer added ``sys.path`` for local workers, only \ 
for remote connections.
  This behavior is surprising because it makes xdist runs and non-xdist runs to \ 
potentially behave differently.

Bug Fixes
- Warning attributes are checked to make sure they can be dumped prior to
  serializing the warning for submission to the master node.
