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>

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.
