Auth Context Processor returns user as a Lazy Object, which breaks things

[Eric Holscher]

With the addition in r11621, when a template checks the type or equality of request.user given from the auth context processor, you used to get:

ipdb> type(response.context['user'])
Out[0]: <class 'django.utils.functional.SimpleLazyObject'>

Previously, this returned an auth.User object.

<class 'django.contrib.auth.models.User'>

Attached is a test that fails with the current trunk. It passes with the current test structure and pre-r11621 auth context_processor.

Note that I meant r11623

I have a very simple use case:

Filter:

@register.filter
def is_equal(obj, arg):
    "Returns a boolean of whether the value is equal to the argument"
    return obj == arg

Template (assuming a user is logged in):

{% if user|is_equal:book.user %} do something {% endif %}

This currently returns False if the user is in fact the same as the book user since it's being evaluated against 'SimpleLazyObject' instead of the actual user object.

This was also referenced on django-users as well:

The attached test is not helpful, because it is effectively doing type checking. But testing for equality with a SimpleLazyObject-wrapped object ought to work, and that will be fixed.

(In [11637]) Fixed #12060 - equality tests between User and SimpleLazyObject-wrapped User failed.

Also added more tests for SimpleLazyObject

Thanks to ericholscher for report.
