/*
 * fetchWrapper(obj)
 *
 * Params:
 *   An Object with the following attributes :
 *     url - string - url of the end point to call
 *     param - object - param to send with fetch call (eg. header)
 *       param.method - string - REQUIRED - method of the http call
 *     actionName - string - name of the action to dispatch with 'PENDING' and 'SUCCESS' respectively before and after the http request
 *     dispatch - func - redux dispatcher function
 *
 * Returns:
 *   An object Response generated by whatwg-fetch with a new property 'json' containing the data received or informations in case of failure
 *
 * This function create a http async request using whatwg-fetch while dispatching a PENDING and a SUCCESS redux action.
 * It also adds, to the Response of the fetch request, the json value so that the redux action have access to the status and the data
