SettingsProvider: Migrate STATS_COLLECTION to secure.

  Migrate STATS_COLLECTION to secure from system table while
  retaining the user preference. Moving it to secure allows us
  to do per-user settings.

Keyguard: Enable quick unlock (1/2)

old way does not work anymore exactly like before. So adapt the idea to new LP code

Thankd DVTonder for the basic idea prior LP

PS:
- do PIN view correctly
- Hide OK button if quick unlock is enabled on PIN view

Keyguard: Correctly set the visibility

What a day. Small derp due that the keyguard does not gets every time reinflated
we need to ensure that the visibilities are set correctly if the user changed the
configuration.

Sorry for 2 fix commits today
