Fixed UpdateBuilder.update() / DeleteBuilder.delete() always return 0 when WAL enabled

1. The root cause is the same as referred in https://github.com/j256/ormlite-android/pull/131
2. Maybe reflection is necessary, execSQL returns void, but executeSql returns correct value
3. Calling methods in a compatible way has been verified and correctness is guaranteed, if executeSql failed, call execSQL
