Accept file deletion requests by clients during sync

- Remove unused full_corpus boolean. The full_corpus=False code path
  wasn't being used (accept for in a test)
- The full_corpus=True code path used was ignoring file deletion
  requests sent by clients during sync. Unclear why this was done
- Added unit test to prevent regression and show file deletion by
  clients during sync not ignored now
