Steps to reproduce:
1. Create a new project with the HDRP template
2. After Unity Editor finishes loading, close it
3. Open Editor.log and search for:
"[Package Manager] Server::Kill -- Server was shutdown
Cleanup mono
Culling group was not disposed. You have to call Dispose explicitly from the main thread. This will likely result in a crash."

Expected result: the error stated above is not found
Actual result: the error is found in the Editor.log

Reproducible with: 2018.4.15f1, 2019.2.17f1, 2019.3.0f4. 2020.1.0a18 (HDRP 4.1.0.preview - 7.1.7)
Could not test with: 2017.4 (No Package Manager)
