Conversations not loading - TypeError in InboxMessagePreview widget

[marc-farre]

Original post: https://community.humhub.com/content/perma?id=279398

Seams to be a database integrity issue.
However, it should still load, ignoring missing conversations.

The issue is the return type of InboxMessagePreview::getMessage() which is Message and, I think, should be changed to ?Message.
But we need to check the consequences of this change.

Log:

TypeError: humhub\modules\mail\widgets\InboxMessagePreview::getMessage(): Return value must be of type humhub\modules\mail\models\Message, null returned in /var/www/html/carrotsocial/protected/modules/mail/widgets/InboxMessagePreview.php:59
