[IOS] Fixes Passwords detail text color in Chrome Settings page

The root cause was that item of type ItemTypeSavedPasswords was not
being properly formatter in |-collectionView:cellForItemAtIndexPath:|

Also sets the detail text of the item at the time of creation, and not
only when the preference changes.
