  For each directory, run vitest sequentially.

  This is done to make sure that the tests are isolated from which other.
  
  Using no-threads parameter removes the per-module isolation as well, but 
  not using the no-threads parameter causes tests to fail beccause there
  is no isolation at the test DB level and different tests can interefere
  with each other's mutations.
