Cleanup password field if it's not set

[BDav24]

When I click on "Change password", then "Cancel", the password param is sent with an empty value, which gives the error: no such column: password

I suggest changing encryptPassword function to:

const encryptPassword: Before = async (request) => {
  const { method } = request
  const { [passwordProperty]: newPassword, ...rest } = request.payload || {}

  if (method === 'post') {
    return {
      ...request,
      payload: {
        ...rest,
        ...(newPassword ? { [encryptedPasswordProperty]: await hash(newPassword) } : null)
      },
    }
  }
  return request
}
