Issuing a credential with a schema OOBI that has problems should give you more explicit error messages

Environment

Docker

Expected behavior

When there is an issue with a schema OOBI one would expect the error to be logged.

Actual behavior

With the default log level, KERIA doesn't detail what is wrong with a schema OOBI. Issuing a credential just fails saying that you first need to resolve an OOBI. It is only when I set the log level to DEBUG that I found that the OOBI endpoint is returning the wrong Mime Type. I would suggest that error messages like that should be sent to the ERROR log level so that it is obvious what the problem is.

Steps to reproduce

Create a Schema OOBI that has some issue like wrong mime type and then try to use it in issuing a credential.
