nuxeo-distribution-tools must correctly filter dependencies when it finds itself in the tree

When nuxeo-distribution-tools (the plugin) finds itself in the dependency tree (in the same version), it fails at filtering its own dependencies.

The following fails when running nuxeo-distribution-tools to build an assembly:
<dependency>
<groupId>org.nuxeo.build</groupId>
<artifactId>nuxeo-distribution-tools</artifactId>
<version>1.5</version>
<scope>provided</scope>
</dependency>
...
<plugin>
<groupId>org.nuxeo.build</groupId>
<artifactId>nuxeo-distribution-tools</artifactId>
<version>1.5</version>
<extensions>true</extensions>
</plugin>

The following works (1.5.0 is an exact duplicate of 1.5):
<dependency>
<groupId>org.nuxeo.build</groupId>
<artifactId>nuxeo-distribution-tools</artifactId>
<version>1.5.0</version>
<scope>provided</scope>
</dependency>
...
<plugin>
<groupId>org.nuxeo.build</groupId>
<artifactId>nuxeo-distribution-tools</artifactId>
<version>1.5</version>
<extensions>true</extensions>
</plugin>
