[MWAR-220] dependencyManagement && overlay + transitive dependency = multiple versions of same dependency in WEB-INF/lib

With dependencyManagement section defined I get multiple versions of spring libraries in target/cas-*/WEB-INF/lib after mvn package. If I remove the dependencyManagement section then only one version of the spring libraries are found.

There seems to be a problem with m-war-p and overlays and dependencyManagement not using the maven GAV resolver in a proper way.. I attached a simple pom which exhibits the problem, just run mvn package to verify.

Start with the attached pom.xml and run mvn package to reproduce the duplicate Spring libraries in target/cas-*/WEB-INF/lib. Trace dependencyManagement and overlay handling in the Maven WAR Plugin, then verify that the packaged WEB-INF/lib contains only the expected dependency version.
