Description

When you try to run a specific shell, and that shell can't be imported, you get a traceback with an unhelpful error message:

$ ./manage.py shell -i bpython
Traceback (most recent call last):
  File "./manage.py", line 22, in <module>
    execute_from_command_line(sys.argv)
  File "/Users/inglesp/.pyenv/versions/inglesham-gallery/lib/python3.6/site-packages/django/core/management/__init__.py", line 367, in execute_from_command_line
    utility.execute()

    raise ImportError("Couldn't load any of the specified interfaces.")
ImportError: Couldn't load any of the specified interfaces.

Instead you should get CommandError explaining what's gone wrong.

I have a PR which comes from my first attempt at fixing #27670.
