[MDEP-726]: dependency:copy finds missing versions in TRANSITIVE depend…

[mkarg]

Status

This PR is a work-in-progress, as the solution is still under construction.

Description

This PR solves MDEP-726 by replacing the original version lookup (which was limited to direct dependencies and managed dependencies) by a code variant which performs a real transitive resolution. As a result, missing version numbers are working fine when copying transitive dependencies.

Help Wanted

While this PR works well with real projects, it fails in the existing unit test with NullPointerException, due to missing GAV coordinates in the test mockup. If someone has an idea how to fix it, please tell me! :-)
