Remove a namespace conflict that restricted parametrize names

Prior to this the arguments that were given to test functions were
limited by other arguments used when passing them around.

This is fixed by the use of the syntax introduced in PEP 570 to ensure
those arguments specific to the plugin are positional only

Fixes #17
