Use existing limit instead of default limit when lazy loading members (#2682)

Browse source 
This should fix an issue where we return less than the expected membership events, when doing an initial sync.
When doing an initial sync, the state limit is set to `math.MaxInt32`, while the default filter is set to 20.
