fix(FEC-13685): Captions advanced settings text style is not saved

### Description of the Changes

**Issue:**
Captions style is not saved
The bug only affected captions style because other uses of storage
manager used StorageWrapper getItem directly

**Fix:**
Add return statement to BaseStorageManager.getItem and do not use
StorageWrapper getItem directly outside of BaseStorageManager.getItem

Resolves FEC-13685
