Étienne Beaulé 4b6dfe1622 Fixed #30542 -- Fixed crash of numerical aggregations with filter.
Filters in annotations crashed when used with numerical-type
aggregations (i.e. Avg, StdDev, and Variance). This was caused as the
source expressions no not necessarily have an output_field (such as the
filter field), which lead to an AttributeError: 'WhereNode' object has
no attribute output_field.

Thanks to Chuan-Zheng Lee for the report.

Regression in c690afb873cac8035a3cb3be7c597a5ff0e4b261 and two following
commits.

Django is a high-level Python Web framework that encourages rapid development
and clean, pragmatic design. Thanks for checking it out.

All documentation is in the "``docs``" directory and online at
https://docs.djangoproject.com/en/stable/. If you're just getting started,
here's how we recommend you read the docs:

* First, read ``docs/intro/install.txt`` for instructions on installing Django.

* Next, work through the tutorials in order (``docs/intro/tutorial01.txt``,
  ``docs/intro/tutorial02.txt``, etc.).

* If you want to set up an actual deployment server, read
  ``docs/howto/deployment/index.txt`` for instructions.

* You'll probably want to read through the topical guides (in ``docs/topics``)
  next; from there you can jump to the HOWTOs (in ``docs/howto``) for specific
  problems, and check out the reference (``docs/ref``) for gory details.

* See ``docs/README`` for instructions on building an HTML version of the docs.

Docs are updated rigorously. If you find any problems in the docs, or think
they should be clarified in any way, please take 30 seconds to fill out a
ticket here: https://code.djangoproject.com/newticket

To get more help:

* Join the ``#django`` channel on irc.freenode.net. Lots of helpful people hang
  out there. See https://en.wikipedia.org/wiki/Wikipedia:IRC/Tutorial if you're
  new to IRC.

* Join the django-users mailing list, or read the archives, at
  https://groups.google.com/group/django-users.
