Title: Fix NilClass exception when assigning a taggable attribute to empty string

When you assign empty string to a taggable attribute, parse_csv returns nil instead of an empty array. This causes the parse_tags method to fail with a NilClass exception.

I've added a spec that fails without the patch and passes with the patch to verify this behavior.
