Before this commit, when having an array of data to insert
in a model, we had to iterate and insert data item on by one:
```js
messageDataList.forEach(data => this.store.Message.insert(data));
```
With this commit, we can simply insert the array of data to
insert:
```js
this.store.Message.insert(messageDataList);
```
This helps simplifying the business code further, less LOCs is
usually better!
