Can not load the second scene in the assetbundle, when there are two scenes in the assetbundle.

Tested both, the new and the legacy assetbuild system on 5.0.0f4. Reproducible on 5.0.0f versions;

Repro steps:
1. Open project "2099_LoadABScene_Multi.zip";
2. In menu bar press "Assets -> Build scene" (it uses the legacy system);
3. Press play, then press the two buttons in the game view, only "level 1" will be loaded;
4. In menu bar press "Assets -> Build scene auto" (it uses the new system);
5. Press play, then press the two buttons in the game view, only "level 0" will be loaded;
