CollabSnapshot "Save to file" logs even with Collab disabled.

Profiling the editor shows that the time is spent in “Unaccounted time
between PlayerCleanupCachedData and GPUProfiler.EndQueries”.

Steps To Reproduce:
prerequisites: have a project with Collab enabled.
1. Launch Unity from command line with the argument "-enableCollabEventLogs"
https://docs.unity3d.com/Manual/CommandLineArguments.html
2. Open project with Collab enabled and press play or make a commit.
3. Turn Collaborate off.
4. Exit Unity.
5. Relaunch Unity from command line with the same "-enableCollabEventLogs" argument
6. Open project that previously had Collab enabled.
7. Enter Play mode and exit play mode a few times
8. Exit Unity and read editor.log.
Observe:It will have the logs: [CollabSnapshot::SaveToFile]

Expected Result: Collaborate should not log anything if disabled.
Actual Result: Collaborate call the [CollabSnapshot::SaveToFile] function.
