 * Calls the function and prevents it from throwing an error.

 * You can use this function to safely execute any other function.
 * @param fn - function to call.
 * @returns A tuple with either true on the first place and date on the second if the call
 * is successful, or false on the first place and error on the second if something went wrong.
