[keyserver] Transform client IDs when handling socket message

Summary:
When receiving a socket message, the server wasn't transforming the IDs - it caused verifyCalendarQueryThreadIDs to throw because none of the received thread filter IDs were present in the DB.

Test Plan: Add and remove some thread filters and check if the error message no longer occurs. Also check if the actualizedCalendarQuery is correctly updated in the store.
