Overlays in asset explorer only show for repositories with a remote

[meaghanlewis]

Description

Steps to Reproduce

1. Create a new Unity project and initialize the GitHub extension
2. Initialize the project
3. Add some new assets to the project
4. Open the Project view and look under assets.

Expected behavior:
Overlay on new or modified assets should appear.

Actual behavior:
The overlay does not appear on assets without a remote.

The piece of code that needs to be fixed is here:

Unity/src/UnityExtension/Assets/Editor/GitHub.Unity/UI/ProjectWindowInterface.cs

Lines 29 to 44 in 484d6a9

	private static bool IsInitialized { get { return Repository != null && Repository.CurrentRemote.HasValue; } }
	public static void Initialize(IApplicationManager theManager)
	{
	EditorApplication.projectWindowItemOnGUI -= OnProjectWindowItemGUI;
	EditorApplication.projectWindowItemOnGUI += OnProjectWindowItemGUI;
	manager = theManager;
	if (IsInitialized)
	{
	Repository.StatusEntriesChanged += RepositoryOnStatusEntriesChanged;
	Repository.LocksChanged += RepositoryOnLocksChanged;
	ValidateCachedData();
	}
	}
