[MNG-6058] Test dependencies should override application dependencies only during testing

**[Christian Schulte](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=schulte77)** opened **[MNG-6058](https://issues.apache.org/jira/browse/MNG-6058?redirect=false)** and commented

The following graph

```
POM
|->a 2.0 compile
|-->b 2.0 compile
|->b 1.0 test
```

will be mediated to

```
POM
|->a 2.0 compile
|->b 1.0 test
```

The test dependency on b will make the transitive application dependency on b disappear. Maven should understand that the application dependency on b in version 2.0 is part of the application classpath and that the test dependency on b in version 1.0 is part of the test classpath only (overriding the application classpath). If someone adds a dependency on a project like that, the test dependency will disappear because the test scope is not transitive so that a "consuming" project gets a different application classpath than the project itself.
