Add a flag to control the concatenation of exception messages

[saken14]

It would be a good if there was a flag to control the concatenation of exception messages in case when I want to display real exception message for users insead of message + stack trace as a string. Please add the ability to remove a stack trace in exceptions.

For example I faced with this: "ORA-20029: ORA-06508: PL/SQL: could not find program unit being called

#0 /var/www/claim/app/Traits/EsbdEntry.php(306): App\Repositories\Api\EsbdRepository->set()
#1 /var/www/claim/app/Traits/EsbdEntry.php(86): App\Tasks\SetClaimTask->setEsbdMethod()
#2 /var/www/claim/app/Tasks/SetClaimTask.php(157): App\Tasks\SetClaimTask->setVictimObjectsEsbd()
#3 /var/www/claim/vendor/spatie/async/src/Task.php(15): App\Tasks\SetClaimTask->run()
#4 /var/www/claim/vendor/spatie/async/src/Runtime/ChildRuntime.php(26): Spatie\Async\Task->__invoke()
#5 {main}".
But actually I need only real message without stack trace - "ORA-20029: ORA-06508: PL/SQL: could not find program unit being called"

The code which is doing concatenation is in "vendor/spatie/async/src/Output/SerializableException.php:29" - $throwable = new $this->class($this->message."\n\n".$this->trace);

Now, I did a temporary solution for that by splitting a string by "\n\n".

$message = $exception->getMessage();
$pos = strpos($message, "\n\n");

if (!$pos) {
    throw $exception;
}
// убираем stack trace который spatie/async добавляет в Exception
$message = substr($message, 0, $pos);
$exceptionClass = get_class($exception);

throw new $exceptionClass($message);
