Fan Zhang 7b77cf8938 Fix suggestion crash if parser fails to parse dismiss rule
We store a index value in shared pref to figure out when a suggestion
should be displayed next time. However the rule can change due to
various reasons. When the index and the rule itself go out of sync, we
should not crash.
