Duplicated definition of built-in magic aliases after %reset

See original GitHub issue

When running %reset -f in Jupyter notebook or Spyder, the following message will be printed.

ERROR:root:Invalid alias: The name clear can't be aliased because it is another magic command.
ERROR:root:Invalid alias: The name more can't be aliased because it is another magic command.
ERROR:root:Invalid alias: The name less can't be aliased because it is another magic command.
ERROR:root:Invalid alias: The name man can't be aliased because it is another magic command.

However, running %reset -f in IPython itself is just fine.

I started experiencing this after upgrading to IPython 7.3.0, and I believe that this behavior was from the change #11528. Maybe those aliases should only be redefined when running in the IPython shell, not in Jupyter or Spyder as a kernel.

In Spyder, using ipython 7.5, every execution still shows this at the beginning: ERROR:root:Invalid alias: The name clear can’t be aliased because it is another magic command. ERROR:root:Invalid alias: The name more can’t be aliased because it is another magic command. ERROR:root:Invalid alias: The name less can’t be aliased because it is another magic command. ERROR:root:Invalid alias: The name man can’t be aliased because it is another magic command.

My new conda update procedure: conda update --all conda install ipython=7.2.0

I’d like to stay up-to-date in ipython. However, continued use of version 7.2.0 seems like the “lesser of evils”.
