view is missing in context when using OrderingFilter

[auvipy]

I can see another view here queryset, view, {'request': request}), would you mind sharing more detail, please? also the tests are failing

added some tests. Without this change self.context in get_field_names and may be other places throws KeyError exeption for missing 'view'

"view is missing in context when using OrderingFilter" isn't a sufficient justification for changing the behaviour here. Even minor changes like this might introduce alterations in our users test cases, and cause unneccessary busy-work all round.

This looks like it might potentially be an okay kind of minor change, but we should have a much higher bar for acceptance.

Ie... a discussion phase where someone has demonstrated that this is more consistent with other places we're passing context around.
