This pull request adds a hook to the isGroupSummary method of android.app.Notification to always return false in the SystemUI hook. There are no review comments, and I have no additional feedback to provide.

Sorry @SoClear, it was working for me and I thought a crash was from another unrelated app and didn't check. I updated the PR and it works without crashing by hooking NotifCollection.postNotification to discard group summaries before they enter the collection, which prevents the StatusBarNotification key mismatch that caused the crashing.
