Updated Data Saver blacklist assumptions.

On Android N, Data Saver's whitelist and blacklist UIDs were stored
separately, hence it would be possible for app to be present in
both (although only through adb commands - the UI only allows one
state).

Now the both lists are stored in the same data structure (UID policies),
hence they comply with the Highlander rule: There Can Be Only One.
