ShouldBeUnique trait is ignored when generating status rows in database

[oobi]

When queueing/monitoring a job with the ShouldBeUnique trait, the dispatch should not result in duplicate status rows in the DB.

I made a quick and dirty modification to Trackable.php based on a comment in the Lumen repo which sorts it out, but there's probably a cleaner way through:

protected function prepareStatus(array $data = [])
    {
         // > New condition
         if ($this instanceof ShouldBeUnique) {

            $uniqueId = method_exists($this, 'uniqueId')
                    ? $this->uniqueId()
                    : ($this->uniqueId ?? '');

            $cache = method_exists($this, 'uniqueVia')
                        ? $this->uniqueVia()
                        : Container::getInstance()->make(Cache::class);

            $uniqueFor = $this->uniqueFor ?? 0;

            $lock = $cache->lock( 'laravel_unique_job:' . get_class($this) . $uniqueId, $uniqueFor);

            // this job is already queued and should be unique. Do not track.
            if (true !== $lock->get()) {
                $this->shouldTrack = false;
            } else {
                // release the lock if we locked it, otherwise it won't queue
                $lock->release();
            }
        }
        // <

        if (!$this->shouldTrack) {
            return;
        }

        /** @var JobStatus */
        $entityClass = app(config('job-status.model'));

        $data = array_merge(['type' => $this->getDisplayName()], $data);
        /** @var JobStatus */
        $status = $entityClass::query()->create($data);

        $this->statusId = $status->getKey();

        return;
    }
