Do not replace json by json_array when making an Entity

[vbourdeix]

When I create an entity with make:entity and type json for the type of a field, it is replaced by json_array, which is deprecated since Doctrine 2.6 if I remember well.

There already has been a pull request to remove the support to json_array, yet I have this behaviour. When I look at the code, the only place (inside the MakerBundle) I can found the json_array string is in src/GeneratorTwigHelper.php but I don't know if this is related, because if there is a possibility of extending the types managed by the maker bundle (didn't search deep enough to know), this behaviour could come from another bundle.

As a side note, the json_array is displayed among the "Other Types" section.

It's due to the autocomplete :

If yout type Enter, json_array is filled instead of json

Autocomplete is based on Doctrine\DBAL\Types\Type and json_array is before json that's why he's trigger before

Then it would be a good idea to remove json_array of the possibilities, right ? If necessary I can make a pull request for this.

As explained on #448, I fully agree with @vbourdeix
Help needed to remove json_array from the types :)
