Wrong placeholder ear created

When a WarModule is created a placeholder ear is Always created. When a module that have a child WarModule but is NOT a ear module a ear placeholder is created but this ear in truth dont exist.

Just take a look in the ServiceModule jbossweb-tomcat55.sar. The JMX-Console show it like a ServiceModule and a like a J2EEApplication.

This patch just take a look if the parent module is a EAR, otherwise WebModule use the J2EEServer as the parent.
