wrong hoogle database for multi-library packages

[Lysxia]

For example https://hackage.haskell.org/package/vector-0.13.2.0/docs/vector.txt currently shows data for the vector:benchmarks-O2 sublibrary instead of the main vector library. I would hazard a guess that Hackage is generating two hoogle databases with the same file name, so one overwrites the other.
