Before this PR the error message would not be super helpful and may
potentially make it hard to debug and report errors. This PR does the
following:
* Add a better error message which also adds comparison of the args with
  which we create the whl library.
* Add a test that ensures that the error message is legible and works.
* Add the necessary plumbing to logger to allow for testing error
  messages.

A proper fix requires more work, so just adding better logging and error
messages may be useful here.
