Reproduction steps:
1. Open the attached project;
2. Check if "Split Application Binary" in Player Settings is checked;
3. Build the project on the device;
4. In the app click a button "WRONG NAME" and then a button "Open Next Scene" (the app crashes);
5. Open the app, in there click a button "PROPER NAME" and then a button "Open Next Scene";

Actual result: the second scene is not loaded.
Expected result: the second scene should be loaded.

Note: the second scene is loaded when before pressing a button "Open Next Scene", the app is minimized and then maximized (it goes like pause and resume processes). After the pause and resume processes, Unity automatically checks if .obb file is available and loads it. However, there is no method in Unity which checks and loads .obb file when it is available, without making the specific pause and resume processes.

Reproduced with: 5.5.0b1, 5.5.4p1, 5.6.2p2

Cannot be tested with 2017.1 and 2017.2 versions because the app crashes. The crash is caused by enabling "Split Application Binary" setting and choosing Gradle (New) in Build System. Also, cannot be tested with 5.4 because there is no Build System setting.
