Potential fix/hack.  Uses getVersionRange instead of getBaseVersion in the map key.

> DefaultDependencyTreeBuilder does not seem to handle managed version ranges.  I have attached a JUnit test that throws the NPE.
> I ran into this issue when using the maven-bundle-plugin, which uses DefaultDependencyTreeBuilder.  I've also attached the full maven project that reproduces this.  The scenario is:
> bundle-all-test: root project, defines dependency on log4j with a *version range* and runtime scope in dependencyManagement 
> proj1: jar project depending on log4j, reducing scope to compile 
> proj2: pom project depending on proj1
> To reproduce, run 'mvn org.apache.felix:maven-bundle-plugin:bundleall' in the proj2 directory.
