issue related to MAGNOLIA-1345

when a /modules/<modulename> config is available in the config repository without a proper module definition magnolia adds a fake module definition and then tries to load a class named "" throwing a classNotFound exception.

This happens when you try to install the workflow module without the dms one: the workflow modules add commands into the /modules/dms/... path, so at restart this is what happens:

WARN info.magnolia.cms.beans.config.ModuleRegistration ModuleRegistration.java(addAdHocDefinitions:206) 08.02.2007 22:47:33 no proper module definition file found for [dms]: will add an adhoc definition
