chore: correct ModuleNotFoundError() arguments

Previously in commit 233b79ed442aac66faf9eb4b0087ea126d6dffc5 I had
used the `name` argument for `ModuleNotFoundError()`. This basically
is the equivalent of not passing any message to
`ModuleNotFoundError()`. So when the exception was raised it wasn't
very helpful.

Correct that and add a unit-test that shows we get the message we
expect.
