Test's `--include-dependencies` is ignored when `--cascade` is set

[Duhemm]

Looking at bloop.engine.Interpreter, it looks like --include-dependencies is ignored when --cascade is set in a test run (this is the only reference to includeDependencies):

bloop/frontend/src/main/scala/bloop/engine/Interpreter.scala

Lines 342 to 346 in f69dd3b

	if (!cmd.cascade) {
	val projectsToTest = {
	if (!cmd.includeDependencies) userDefinedProjects
	else userDefinedProjects.flatMap(p => Dag.dfs(state.build.getDagFor(p)))
	}

I don't see why --cascade should exclude --include-dependencies. This should be either fixed or documented.

My expectation is that --cascade could be combined with --include-dependencies, but --cascade shouldn't implicitly enable --include-dependencies.
