Fix index lookup

[jedelbo]

Constructing a ObjKey from a value read in the index went wrong.

I use RealmSwift on iOS, and when accessing a filtered Results count property e.g. searchResults.count it would crash sometimes with Crashlytics reporting "Key not found", so I think this should fix it - could you confirm and please let me know if it's not. Thanks!

@hyouuu It is hard for me to tell without knowing your specific query, the size of the database and the values you are querying for.

@jedelbo one of the crashes' predicate is type ==[c] "calendar" where type is a String property on the realm object; size of the database is about 7000 records

@hyouuu I would say there should be some links involved for you to be affected by this.

@jedelbo with the latest version I'm still seeing crash reports regarding Key not found - I did upgrade from 4.3.0 to 5.3.7. Could you check if there could be other causes to the problem? Thanks!

Would use v10 fix the problem?
