In AuditorFactory.java in method autoConfig, the autoConfigFileByProperty should not be prefixed with pathPrefix when creating URL.

For example, if the system property is set as:
-Dlogback.audit.autoconfig.file=file:///${com.sun.aas.instanceRoot}/config/logback-audit.xml

and client application name is set as appname then URL will be set to:
appname/file:///${com.sun.aas.instanceRoot}/config/logback-audit.xml

This bug results in configs only being set via AUTOCONFIG_FILE which complicates multi module projects resulting in multiple config files instead of just using one at the domain level.
