[MASSEMBLY-1008] Fix transitive dependencies resolving with required scope

[cstamas]

This IT demonstrates how assembly plugin (among others) does it wrongly, as the plugin code probably originates from Maven2 times.

What happens:

• "single" mojo resolves test project dependencies (see Mojo annotations)
• then it reads assembly descriptor (so it only learns now what user wants)
• then uses resolved project dependencies to deliver descriptor contents

But, here is a problem that IT demonstrates: the delivered list of files are NOT runtime scoped, they are "test scope filtered for runtime leaves" which is not the same thing. By the way, dependency plugin demonstrates same behavior: wrongly assumes that "test" graph is super set of "runtime" tree, but that is not true nor was never true since Maven3 (resolver), it was true ONLY in Maven2 times.

The proper runtime graph of IT project as shown by resolver is this:
