[IL2CPP] Async operation causes NullReferenceException in the Build when Scripting Backend is IL2CPP



How to reproduce:
1. Open the attached project
2. Make sure that the Scripting Backend is set to IL2CPP
3. Build the project
4. In the Visual Studio, select "Debug/ Attach Unity Debugger"
5. Launch the Build
6. Select it in the "Select Unity Instance" window
7. Hit "Play!" in the Build

Expected result: NullReferenceException is not caused (just like when Mono is set as a Scripting Backend)
Actual result: NullReferenceException is caused.

Reproducible with - 2018.1.9f2, 2018.2.6f1, 2018.3.0a11

Note: Not tested on versions prior 2018.1, since support for IL2CPP scripting backend for Windows Standalone was not yet introduced.

Fixed in 2019.1.0a3
Backported to 2018.2.11f1, 2018.3.0b3
