[client-sync] Don't throttle while syncing first 500 threads

Browse source 
Summary:
We want to get to a usable inbox as quickly as possible, and throttling
prevents this. We should basically only be throttling for historical
mail syncing.

Test Plan: Run initial sync benchmark, it's 117% faster on battery
