Update SQLiteQueryBuilder to match aosp-master and internal master

SQLiteQueryBuilder.appendWhere and appendWhereEscapeString
has @NonNull in master and aosp-master however not in staging.
This breaks the build in staging now the tool that generates
current.txt includes annotations in the signatures.

Test: lunch aosp_taimen-userdebug && make -j
