Fixed retrieving non-initialized wallpaper information

When an attempt is made to retrieve wallpaper information such
as getWidthHint during user switching, the wallpaper may be
uninitialized and therefore throw NullPointerException.

Resolved by initializing wallpaper for current active user
if not yet initialized or returning null if applicable.

SystemUI: disable statusbar time refresh when screen off

When screen is off, don't refresh the status bar to save power.
When screen is on, refresh immediately for user experience.
