Removed warning when objects are added on wrong order.

append() is used to optimized insertions in the array, but it must
preserve the order of the hashcode array; when it doesn't, it falls back
to append(), but it should not log a warning message

In particular, PendingIntentRecords might have different hashcodes
across different processes.
