[libgpiod][PATCH 1/3] bindings: python: tests: extend reconfiguration tests

[Kent Gibson <warthog618@gmail.com>]

A number of the corner cases for reconfiguration are untested, including
 - using None for default settings
 - missing settings for some lines
 - jumbled line ordering relative to the request
 - extra settings for non-requested lines

Add tests for these corner cases.
