Tests for Sphinx's CLIs, like test_apidoc, indirectly init_console to
initialize translations for Sphinx's console domain, the one with
Sphinx's log messages. This bleeds over subsequent tests by making
warnings translated. Fix this by skipping init_console when running
Sphinx's test suite.

.. note::

   $ find sphinx tests LICENSE doc/conf.py -type f -exec sed -i '' -e 's/2007\-20../2007-2021/' {} \;
   $ git co sphinx/locale/**/*.js sphinx/templates/epub3/mimetype

Keep imports alphabetically sorted and their order homogeneous across
Python source files.

The isort project has more feature and is more active than the
flake8-import-order plugin.

Most issues caught were simply import ordering from the same module.
Where imports were purposefully placed out of order, tag with
isort:skip.
