ref(wsgi): Drop send_default_pii support in RequestExtractor

[ericapisani]

Always derive request cookies and body collection from data_collection instead of falling back to send_default_pii when it isn't configured.

Remove the Django cookie-scrubbing tests that depended on send_default_pii, and switch the remaining Django tests to data_collection={}
