Take scope into account when synchronizing pom

• Add a unit test for an automation operation
• Synchronize pom
  => A dependency to nuxeo automation core is added with the test scope

<dependency>
      <groupId>org.nuxeo.ecm.automation</groupId>
      <artifactId>nuxeo-automation-core</artifactId>
      <scope>test</scope>
</dependency>

• Add an automation operation
• Synchronize pom
  => No dependency is detected (should be nuxeo automation core without test scope)
  => Take into account existing scope when detecting dependencies

Workaround: remove the test dependencies and synchronize pom again
