[Sync] Fix Syncing Cleared Preferences bug

Before this CL:
Upon clearing a pref on the client, sync would push the default of the
pref to the server and other clients.
This is wrong because other clients cannot tell if the user has
actually cleared the pref or intentionally set it to the default value.

After this CL:
Upon clearing a pref on the client, sync would remove the pref from
the server and other clients.
