I'm not yet 100% sure what's going on, but the old code, not stopping
the scheduled forceLoad() in onReset() is apparently wrong.
onReset() is a new callback introduced in the recent loader change, so
this can explain why it started after the change.
Also, call super.onContentChanged() instead of directly calling forceLoad(),
as Loader.onContentChanged() now does more than just calling forceLoad.
