bookmark: Fix the bookmarks duplicated/misplaced logic

 * Create a most popular model in PhoneDirectoryModel
 * Un-duplicate ContactMethod::roleData
 * Make the changes to CategorizedBookmarkModel to act as a proxy

I came to the conclusion the old code path was unfixable and its logic
could not be fixed. The fact that it was duplicating data that could
change without much notice made it too prone to desynchronization.
