⚡️ Improved GScan performance for themes with many partials

refs https://github.com/TryGhost/DevOps/issues/3
refs b6d8e0192a

- see referenced commit for full context but this should improve the
  theme check time for themes with a large number of files and partials
- locally, checking a particularly heavy theme goes from 5s to 1.7s with this
  commit, and the improvement is larger on slower machines
