Index creation should be set different sync/asyn for state-transfer and normal processing

As the creation of the index can be slow for huge caches during state transfer the performance is better if it is processed asynchronous.
But for adding entries during normal, and maybe transactional, processing it is important to being able to run a query right after adding or changing new entries with the correct index.

Therefor the sync/async setting should be separate for state-transfer.
