fix recent changes error (nil updated_at)+solution

This was caused by a data problem: cards with wrong key for their name.

The problem is contained now- (error renders in content doesn't break whole page)

And we've added some data consistency checks (db constraints, validations) but don't know that they will prevent this from happening.
