Queries scoped to remote queries before load fail

[robmonie]

I have a remote query that i'm using as a base query for other queries to scope themselves to for things like further client side filtering and sorting. If I attach the scoped queries after the main query has finished loading, everything works fine. If however, I attach the scoped query before the baseQuery has been loaded, I get "Cannot call method 'forEach' of null" on line 568 of SC.RecordArray - https://github.com/sproutcore/sproutcore-datastore/blob/master/lib/system/record_array.js#L568

I have ways of working around this but it would be simpler if it didn't fail under this scenario.

cheers,
