Fix Trac #1988; keep the ru_fn field of a RULE up to date

The ru_fn field was wrong when we moved RULES from one Id to another.
The fix is simple enough.

However, looking at this makes me realise that the worker/wrapper stuff
for recursive newtypes isn't very clever: we generate demand info but
then don't properly exploit it.

This patch fixes the crash though.
