Delay check for possibly deferred return type for reference candidate

 This issue appeared after recently added new overload for flatMapTo.
 Before that, we picked candidate returning List<T> and completed
 inference, now we also check one more flatMapTo, which is here is
 incorrect and as a result we go into outer scope. Outer scope contains
 one property with deferred type, which introduced error about
 "typechecker has run into recursive problem" even it isn't applicable
 by receiver.

 So, the fix is to check receiver first and only then check return
 type of a candidate.
