Fix issue with post v2.6.13 'new' hook
Fix issue with post v2.6.13 'new' hook

Genesis v2.6.13 removed passing positional arguments to new hook, but if
an error occurred, the error message used those positional arguments.
This changes it to use the environment variables that replaced the
positional arguments.
