[BUG] in GET "/v2/entities/<id>/attrs/<attr_name>/value" with several Accept header

[iariasleon]

in Attribute Value --> By Entity ID --> Get attribute value
GET /v2/entities/<id>/attrs/<attr_name>/value

• If Accept: application/json and the attribute value is number or string or boolean or null returns a json response as {"value":56.000000} or {"value": "34"} or {"value":true} instead of an error message, ex:

HTTP code: 406 Not Acceptable
{
    "error": "NotAcceptable",
    "description": "no defined yet"
} 

• If Accept: text/plain always returns a string, also in number, boolean or null values

Actually, this is already taken into account in issue #1259 part 6. However, let's hold this issue if you want, to make more explicit the need of checking this after #1259 completion from a QA perspective.
