Make knn graph conn writing more consistent #14174

Merged

This fixes two minor inconsistencies.

  • Makes sure that connected components isn't called twice with concurrent hnsw merger
  • make sure that duplicate connections are also handled when a sorted field is used on flush

Note, this does NOT address the merge consistency from: #14172

The test still fails with that seed, but these are two issues I found in that investigation.
