Never attempt to disable grouped CBRS until all SIM states are final.

In grouped primary and CBRS usecase, we may initialize CBRS profile first
and disable it unexpectedly as we believe it's the only active subscription.
We shouldn't do it until both SIMs are initialized (LOADED / ABSENT and
other final states).
