Description Zac Medico gentoo-dev

I've found a case where the depgraph _complete_graph method pulls in an installed package to satisfy a dependency, when that installed package is already scheduled to be rebuilt in the current calculation via the @__auto_slot_operator_replace_installed__ set. This ultimately triggers a slot conflict which prevents the the correct solution from being found. I will post a patch that solves the problem, including a test case.
