Redundant language check causing php erros

I've run into this issue also using date_ical with custom entities (not nodes).

Essentially, there's a line in the views row plugin that tries to grab $entity->language. This doesn't exist on all entities, so you get a php notice in that case; quite a few log entries for a big view!

As it turns out, the variable it's setting is actually entirely unused, so the line can just be removed. Patch to follow.
