I fixed integration test CI in #7310

[nickvergessen]

It seems there is more to gain. While we truncate the description actual, before and after (

deck/lib/Activity/ActivityManager.php

Lines 404 to 419 in 7271d6c

	if (mb_strlen($json) > self::SUBJECT_PARAMS_MAX_LENGTH) {
	$params = json_decode(json_encode($subjectParams), true);
	if ($subject === self::SUBJECT_CARD_UPDATE_DESCRIPTION && isset($params['after'])) {
	$newContent = $params['after'];
	unset($params['before'], $params['after'], $params['card']['description']);
	$params['after'] = mb_substr($newContent, 0, self::SHORTENED_DESCRIPTION_MAX_LENGTH);
	if (mb_strlen($newContent) > self::SHORTENED_DESCRIPTION_MAX_LENGTH) {
	$params['after'] .= '...';
	}
	$subjectParams = $params;
	} else {
	throw new \Exception('Subject parameters too long');
	}
	}

) , on our prod db a lot of activities also have a full size descriptionPrev stored.

🐢 Performance warning.
It looks like the query count of the integration tests increased with this PR.
Database query count is now 83001 was 82774 (+0.27%)
Please check your code again. If you added a new test this can be expected and the base value in tests/integration/base-query-count.txt can be increased.
