Json objects returned as strings for "memory" adapter

[raffaele-clevermind]

When using the memory adapter and saving json objects, like shown in the example below, the objects are converted into strings but when returned from "find" method the values are not converted back:

const caminte = require('caminte'),
    Schema = caminte.Schema,
    config = {
         driver     : "memory",
    };

let schema = new Schema(config.driver, config);
let users = schema.define( 'user ', {
  id: { type: schema.Integer},
  name: { type: schema.String},
  data: { type: schema.Json}
}, { primaryKeys: [ 'id' ] } );


users.create({
  id: 1,
  name: 'raffaele',
  data: {age: 22}
}, () => {
  users.find({where: {}}, function(err, users){
     console.log('users:', users); // the data object is a string
  });
});

From what i see this depends on the fact that the memory driver is handled in the AbstractClass class as a "SQL" adapter, which means that the json values are stringified:

AbstractClass._forDB = function (data) {
    var res = {}, YesSQL = ['mysql', 'sqlite', 'sqlite3', 'firebird', 'memory'];
    Object.keys(data).forEach(function (propName) {
        if ((this.whatTypeName(propName) || '').toString().toLowerCase() === 'json'
            || data[propName] instanceof Array) {
            if (YesSQL.indexOf(this.schema.adapter.name || this.schema.name) !== -1) {
                res[propName] = JSON.stringify(data[propName]);
            } else {
                res[propName] = data[propName];
            }
        } else {
            res[propName] = data[propName];
        }
    }.bind(this));
    return res;
};

But the memory adapter doesn't then parse the values when returning them from methods like "find".
