Include operatorsAliases in sequelize connection.

[DesignByOnyx]

Sequelize now recommends that operator aliases be defined so as to prevent known security issues (read more here).

Sequelize now emits a warning if aliases are not defined. In order to suppress this warning and "follow the rules", the generator should include known aliases:

const operatorsAliases = {
    $in: Op.in,
    $notIn: Op.notIn,
    $lt: Op.lt,
    $lte: Op.lte,
    $gt: Op.gt,
    $gte: Op.gte,
    $ne: Op.ne,
    $or: Op.or
  };
const sequelize = new Sequelize(connectionString, {
    dialect: 'postgres',
    logging: false,
    operatorsAliases,
    define: {
      freezeTableName: true
    }
  });

Makes sense. We'll probably have to update the adapter to use this as well right?

I don't think the adaptor needs to do anything - the only operator being referenced is $notIn. However, if we want we can create an alias for $nin and get rid of that section of code:

const operatorsAliases = {
    ...
    $notIn: Op.notIn,
    $nin: Op.notIn, // this makes the non-standard $nin operator recognized by sequelize
    ...
};
