Fixes #1710. Fixed cached resolution mutual eviction

When stitching the minigraphs together only exclude the artifacts that
were evicted in *all* graphs, instead of some graphs.
Consider the following scenario:
- Y1 evicts slf4j-api 1.6.6 and picks 1.7.5
- Y2 evicts slf4j-api 1.7.5 and picks 1.6.6
At the root level, we need to use our own judgement and pick 1.7.5.
