Unhelpful error when JWT_SECRET_KEY is not set.

[exhuma]

If no secret key is set (that is, None), the following error is reported:

TypeError: Expecting a string- or bytes-formatted key.

A more helpful message would be nice.

This really saved me. I've been debugging a test application that keeps showing this error for hours. Thanks.
