HOVER: Fix a couple of things:

- Handle Ticker properly. Update mTicking, call related statements
  and disable ticker for blacklisted apps only when hover is off.
- Remove a bad patch when you release your finger, there is no need and
  along with showCurrentNotification() call at setNotification() can even
  be a bad call.
- Notification removal is already done at BaseStatusBar. Remove useless code.
