Don't mess around with pref local ID for common settings initialization.

It confuses the pref initialization, causing the back facing camera resolution
being overwritten by the front facing camera resolution.
Instead, make the foll. global (camera independent) setting.

- Power Shutter
- Storage
- TrueView
- Smart Capture
