Lists: Survey response columns don't handle undefined cell values

[ziggabyte]

Description

When adding a column of survey responses to a list, sometimes the organiser gets struck with an annoying "Application error"

@richardolsson says that he has only been able to reproduce this bug with live data, and not fake data, so in that way it's not "entry level" to work on it, BUT he did find what caused the bug and has kindly shared his fix here. So, you probably can't reproduce it, but you can solve it :)
