Additional columns defined in collections.columns show empty on list view if one document in list is invalid

[tyteen4a03]

Additional columns defined in collections.columns show empty on list view if one document in list is invalid. This is especially annoying between schema upgrades.

I'm using GitHub mode but this might also apply to Desktops.

Reproduction Steps

1. Set up additional columns, and display them using the columns option in collections config.
2. Edit a document so that it no longer conforms to the schema
3. View the list of items in the collection. The additional columns all have no value.
