[lib] Modify update calendar query so that it can update a subset of keyservers

Summary:
CalendarQueryHandler will be dispatching this action for a single keyserver - we need to be able to do that. Later in the stack I'm going to move actualizedCalendarQuery into keyserverStore so that it becomes keyserver-specific.

Depends on D11094

Test Plan:
Modify date range on a calendar and check if the query is correctly updated.
Modify the code by setting an explicit keyserver id and check if the solution still works and a keyserver ID is present in the reducer.
