fix: Exclude access to request.user from view

[tartieret]

The django test for access to foreign keys exclude request.user but fails if we do this within a view and use self.request.user. This PR fixes the issue by excluding this common use case in django & django rest framework.

@0xDC0DE sorry to ping you, but I saw that you recently approved another django-related rule and that you work at Semgrep. I am wondering if we could get this merged as it leads to false positive and would be a super quick review?
