Bug: Can't delete board after import

[omggga]

I am writing a modification of importTrello.ts(https://github.com/mattermost/focalboard/blob/main/import/trello/importTrello.ts) for more complete import (including comments, attachments and images). For now everything is ok there, but i had a lot of "broken" boards while were testing import. Some of them doesn't have connections between cards and attachments or images, and the problem is that i cant delete them even having and admin rights.

Steps to reproduce the behavior

1. Import random card from trello with some wrong data
2. Select "delete board"
3. See error in the System console

Expected behaivor

The board is disappeared.
