Waiting for the psim subscriptionInfo ready

When the pSIM is inserted for the first time, this subscriptionInfo arrives late.
It causes the sim onboarding is closed.
We add the timer to wait the psim's subscriptionInfo.

Bug: 377171470
Flag: EXEMPT bugfix
Test: insert the psim and showing the sim onboarding flow.
