[FIX] hr_referral: Fix referral module install

Issue:
The hr_referral application can not be installed with demo data.

Analyze:
The db is being auto locked. And transaction is not rollback due to the
xml failure.

Fix:
Add corresponding line into hr_demo.xml instead of hr_referral_demo.xml

Note:
It does not fix the root cause, but until the root cause is well defined
and fix, it is the best workaround.
