v2.3.27

• Improved support for more complex json-schema's (containing oneOff/anyOf/allOf at the root for example)
• It used to be that storing a string in a JSONB column would not work,
  but that does work now, so it's easier to not worry too much anymore about the datatype
  and use jsonb column for almost everything
• Internal improvements:
  • Improved 'npm run test' to only run a subset of all the tests. You can now run things like:
    npm run test ./testBatch.ts ./testPutAndPatch.ts
  • A few typing improvements.
  • Updated signature of 'query' handlers, so they always have the same signature
    (defaultFilter, queryUtils, relationsFilter + the user's own filters all have
    the same signature now)
