[#2030][2030]/[#1721][1721]/[#2014][2014] by [@eed3si9n][@eed3si9n] sbt 0.13.9 also fixes a correctness issue that was found in the earlier releases.
Under some circumstances, libraries that shouldn't have been evicted was being evicted.
This occured when library `A1` depended on `B2`, but a newer `A2` dropped the dependency,
and `A2` and `B1` are also is in the graph. This is fixed by sorting the graph prior to eviction.
