authentication-local with Sequelize doesn't protect password on Sequelize error

[tdolphin]

Steps to reproduce

1. feathers generate authentication
2. use Sequelize (postgres)
3. users.model.js has email field as unique
4. create another user with same email
5. Sequelize error sent in BadRequest 400 contains password.
6. Add hook to error in users.hooks.js has no effect.
   error: { all: [protect('errors')], find: [], get: [], create: [], update: [], patch: [], remove: [] }
   Tried variation:
   protect('errors[0].instance.password')
   Tried using omit directly with no effect.

Expected behavior

protect/omit in error hooks should have effect

Actual behavior

protect/omit in error hooks not called.
throw feathersError; feathers-sequelize/lib/utils

System configuration

Module versions (especially the part that's not working):
authentication-local 1.2.1
feathers-sequelize 3.1.2

NodeJS version: 10.7

Operating System: windows 10

Browser Version: postman

Module Loader: npm

Similar to feathersjs-ecosystem/errors#115 - basically feathers-sequelzize should not really pass through - or clean up - any of those errors.

Additionally, it is true, the protect hook in https://github.com/feathersjs/authentication-local/blob/master/lib/hooks/protect.js should also do this for context.error

This has been done in the latest feathers-sequelize.
