encoding/jsonschema: add test for Config.PkgName
In the recent jsonschema changes, we had lost the functionality of
adding a package name to the output. There were no tests for this, so
this CL adds a test; the functionality itself will be fixed in the next
CL.
This also updates the error output from the external tests with
respect to some recent evaluator changes.
