Fix Clock flickers after reboot with strong authentication

Browse Source 
After boot, the device request the strong authentication but
finger print is not strong. The keyguard will appear after collapsing
NotificationPanelView.

Because StatusBarKeyguardViewManager.mExpansionCallback.onFullyShown
->updateStates should call mStatusBar.setBouncerShowing(true)
before PanelBar.mExpanded = false but
StatusBarKeyguardViewManager.mBouncer.isShowing() return false,
StatusBarKeyguardViewManager.updateStates doesn't call
mStatusBar.setBouncerShowing.

After PanelBar.mExpanded = false, PhoneStatusBarView post runnable
mHideExpandedRunnable to show the Bouncer and make the Bouncer to be
showing and then change the NotificationPanelView to be VISIBLE.

The solution is to call
mStatusBarKeyguardViewManager.showBouncer(false) before calling
mStatusBarKeyguardViewManager.animateCollapsePanels(
FINGERPRINT_COLLAPSE_SPEEDUP_FACTOR). To make the
KeyguardBouncer.mRoot to be VISIBLE by KeyguardBouncer.mShowRunnable.
