[MNG-1378] Make dependencies of test-jars transitive

**[Mark Hobson](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=mihobson)** opened **[MNG-1378](https://issues.apache.org/jira/browse/MNG-1378?redirect=false)** and commented

test-jar transitive dependencies are calculated as per compile scope rather than test scope.

The situation is demonstrated nicely in it0077:

* module sub1 has a test-scoped dependency of commons-lang
* module sub2 has a test-scoped dependency of sub1 test-jar

sub2 tests should inherit the commons-lang transitive dependency. For example:
