Juan Alvarez 46b2b08e45 [4.2.x] Fixed #34779 -- Avoided unnecessary selection of non-nullable m2m fields without natural keys during serialization.
By using `select_related(None)` instead of `select_related()`, the
unnecessary joins are completely avoided. Note that the current tests
already covers the change, when the field is not `null=True`.

Regression in f9936deed1ff13b20e18bd9ca2b0750b52706b6c.

The documentation in this tree is in plain text files and can be viewed using
any text file viewer.

It uses `ReST`_ (reStructuredText), and the `Sphinx`_ documentation system.
This allows it to be built into other forms for easier viewing and browsing.

To create an HTML version of the docs:

* Install Sphinx (using ``python -m pip install Sphinx`` or some other method).

* In this docs/ directory, type ``make html`` (or ``make.bat html`` on
  Windows) at a shell prompt.

The documentation in ``_build/html/index.html`` can then be viewed in a web
browser.
