When the query's model had a self-referential foreign key, the
compiler.get_group_by() code incorrectly used the self-referential
foreign key's column (for example parent_id) as GROUP BY clause
when it should have used the model's primary key column (id).

This is a regression caused by introducing rendered migration states in
1aa3e09c20 and the _meta refactoring in fb48eb0581.
Thanks to Danilo Bargen for reporting the issue and Marten Kenbeek and
Tim Graham for triaging the bug and providing the initial test case.

The test failed on RHEL6 systems running python 2.7 from a RedHat
Software Collection (SCL) because this test runs an external python
script with a stripped system environment. RedHat SCLs work by setting
a number of system environment variables when these are stripped out by
this test the python 2.7 interpreter is no longer able to function
properly because it can not find the system libraries needed.
Now we use use mock to modify the system environment directly.

Without that, the Note model would be initially created and then
the tests using that model failed when run in isolation.

The only problem for Oracle was the test, which tested nullity on
text/char fields -- but Oracle interprets_empty_strings_as_null.

Fixed queries where an expression was used in order_by() but the
expression wasn't in the query's select clause (for example the
expression could be masked by .values() call)
Thanks to Trac alias MattBlack85 for the report.

Instead of setting ``warning_stream`` in the docutils config overrides
to ``False`` I opted for filtering the stderr in the tests to keep the
error output showing up in server logs.
Thanks Tim Graham for the report and review

This also prevents state modifications from corrupting previous states.
Previously, when a model defining a relation was unregistered first,
clearing the cache would cause its related models' _meta to be cleared
and would result in the old models losing track of their relations.

This change:
* Makes the InclusionNode cache-safe by removing render-time side effects
to its nodelist.
* Ensures the render_context stack is properly scoped and reset by updating
the render call to use Template.render rather than Nodelist.render.

Rendering a Jinja template with self in the context threw an error.
While self is a reserved variable in Jinja, including self in the
context is not an error, so Django should respect that.

When reversing, only outer parameters are used if captured parameters are
nested. Added tests to check the edge cases and documentation for the
behavior with an example to avoid it.
