Throw exception from SystemUiProxy.getRecentTasks for invalid result
- The reason Recents is empty after a force-stop is when RecentsTasksList.getTasks is called first time after restart, the result is always invalid but we cached the invalid result with a chagneId(=1). The next time we call getTasks again, we think the cached result is valid, and returend an empty list.
- The fix is to mark such result as invalid to avoid caching the wrong result
