ipc: don't treat replies with the unblock flag set as regular messages
Old behavior would test should_unblock() before is_reply() so if both were set
but TryToUnblockListener wouldn't return true (the corresponding Send isn't on
top of the stack), it would queue the message as to be dispatched.
This restores the correct order.
