Title: Fix Hidden field bug (check for this.$help)

Check for `this.$help` to avoid errors (Hidden fields don't have error div element)

Bug could be seen when have a List whose NestedModel contained a Hidden field. When editing an item of the list there was an error due to having a field with type Hidden.
