Human readable Incompatible values for 'undefined' and 'undefined'

The issue with 'undefined' and 'undefined' probably lies deeper than a simple raw error message, but this commit at least makes them readable. Where you would usually get the message "Incompatible values for the 'undefined' of 'undefined' linting options" you will now be able to pinpoint the error with actual fields e.g. "Incompatible values for the 'strict' of 'globalstrict' linting options".
