py-test: updated to 5.4.3

pytest 5.4.3:

Bug Fixes
* Paths appearing in error messages are now correct in case the current working \ 
directory has changed since the start of the session.
* Support deleting paths longer than 260 characters on windows created inside tmpdir.
* Prevent pytest from printing ConftestImportFailure traceback to stdout.
* Prevent hiding the underlying exception when ConfTestImportFailure is raised.
* Fix regression where running with --pdb would call the tearDown methods of \ 
unittest.TestCase subclasses for skipped tests.
