Two "Lifecycle ERROR" exceptions thrown on every Editor start for projects when upgraded from an older Multiplayer Play Mode version

Steps to reproduce:

1. Download and extract the attached project
2. Open it
3. Observe the Console once Import is complete

Actual results: 

Two errors are logged on every Editor start / domain reload, and the Multiplayer Play Mode workflow never initializes:

Lifecycle ERROR : Exception while executing scope transition handler Unity.Multiplayer.PlayMode.Editor.MultiplayerPlaymode.InitializeOnLoad(): System.TypeInitializationException: The type initializer for 'Unity.Multiplayer.PlayMode.Editor.VirtualProjectWorkflow' threw an exception. ---> UnityEngine.UnityException: Calls to "AssetDatabase.GetMainAssetOrInProgressProxyEntityId" are restricted during . Please make sure this function is not called from code that runs during code reload (e.g. [OnCodeLoaded])

(the same TypeInitializationException is thrown again from Unity.Multiplayer.PlayMode.Editor.MultiplayerWindowController.InitializeOnLoad())

Expected results: No errors on Editor start; the old-version data migration runs without violating the code-reload restriction and Multiplayer Play Mode initializes normally.
