Revert "TextView: Prevent more NPEs"

This reverts commit 087181eb3cc293bdb30584e37c4e04ab060e08bc.

I dunno why this breaks TextView in Chrome app, get rid of safe checks then! lol
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.
