SyncVar hook isn't called most of the time if SyncVar value is changed during scene change



Steps to reproduce:

1. Open attached project
2. Build and run project as host
3. In editor, open scene "SceneStart" and run it
4. Connect to chost
5. Return to build and start spamming "Enter scene 1"
6. In client (editor) notice that not all SyncVar changes are called

Reproduced with: 5.3.6p2, 5.4.0p1, 5.5.0a5

    The SyncVar hook bug is also likely related to this bug.

    OnSerialize (with initialState=true) is sent on a scene change to all persistent DontDestroyOnLoad networked objects. I believe this is how the SyncVar value is changing on the client, without the hook being called. It appears that persistent DontDestroyOnLoad networked objects are being treated as new network scene objects and "spawned" when the new scene is loaded.
