 For example: `bp_send_email('email_type','4747',[])` not working with
 numeric user id.

 This not working because `is_int( $email_or_user )` used instead of
 `is_numeric()`.

 `__construct` method of BP_Email_Recipient class uses `get_user_by` WP
 function which uses `get_data_by` with `is_numeric()` function for `'id'`

 Therefore, for consistency of behavior need to use `is_numeric()`.
