Add missing pvc namespace to the vrg rdspec

It seems that recent change for supporting multiple namespaces have
broken failover with volsync when using multiple volsync apps. Add the
pvc namespace to the protected pvc, similar to volrep code.

I did not modify the test to validate this change since I don't fully
understand the test. It seems that there is a missing `It` section for
testing the vrg.
