"-quit" CMD argument is not waiting for async operations from Methods with the return type "Task" in batch mode
Reproduction steps:
1. Run the "AsyncExecute2020.zip" project with these command-line arguments: "-batchmode -executeMethod "Builder.Build" -logFile -projectPath -quit"
2. Open the log
3. Note that "Before" is logged
4. Open "Builder.cs" script
5. Comment "Task Build()"
6. Uncomment "void Build()"
7. Run the "AsyncExecute2020.zip" project with these command-line arguments: "-batchmode -executeMethod "Builder.Build" -logFile -projectPath -quit"
8. Open the log
9. Note that "Before" and "After" is logged
Expected Result: "-quit" CMD argument waits for async operations from Methods with all types in batch mode
Actual Result: "-quit" CMD argument is not waiting for async operations from Methods with the return type "Task" in batch mode

Resolution Note (2020.1.X):
-executeMethod does not support methods with a return type other than void and 0 argument and this also applies to async methods. This hasn't been enforced with an error, but we have added this now.
To use a async method that returns a Task with -executeMethod, you can use call a async void method that calls into the Task.
public static async Task AsyncTaskBuild()
{
// code
}
public static async void Build()
{
await AsyncTaskBuild();
}
