StandardOutput handling issues (Moonlight-Qt CLI)

[Searaphim]

Describe the bug
Moonlight-qt CLI doesn't handle stdout in a way that allows for automation.

Steps to reproduce

• Try a simple redirection: ./moonlight.exe list someip > output.txt
• notice how the file is empty even though your list was printed to the console.

Other Moonlight clients

• Most likely not.

Moonlight settings (please complete the following information)

• Have any settings been adjusted from defaults? No
• If so, which settings have been changed? N/A
• Does the problem still occur after reverting settings back to default? N/A

Client PC details (please complete the following information)

• OS: Windows 10 19045
• Moonlight Version: v5.0.1
• GPU: N/A
• Linux package type (if applicable): N/A

Server PC details (please complete the following information)

• OS: Windows 10 19045
• Sunshine or GeForce Experience version: Sunshine [v0.23.1]
• GPU: N/A
• GPU driver: N/A

Additional context

• I suspect that it is because before quitting; Qt is doing it's own redirection to write to the log files.
• You can try binding to stdout in other ways such as C# or C++ and all of them fail to properly catch the output on app exit.
