GetFaviconSuggestions causes an error in AzureFileSystem

In FaviconService.cs the .GetMediaFolders call with "." as parameter causes an
error at AzureFileSystem.cs as it tries to recreate the folder with path "/."
The parameter should change to null if you want it to work with Azure Modules
enabled.

```
public IEnumerable GetFaviconSuggestions() {
List faviconSuggestions = null;
var rootMediaFolders = _mediaService
.GetMediaFolders(".") // change the parameter to null for Azure Storage
.Where(f => f.Name.Equals(FaviconMediaFolder, StringComparison.OrdinalIgnoreCase));
if (rootMediaFolders.Any()) {
faviconSuggestions = new List(
_mediaService.GetMediaFiles(FaviconMediaFolder)
.Select(f => _mediaService.GetMediaPublicUrl(FaviconMediaFolder, f.Name)));
}
return faviconSuggestions;
}
```

Start in FaviconService.cs at GetFaviconSuggestions and inspect the GetMediaFolders call, then review AzureFileSystem.cs to understand the "." path failure. Change the parameter as described and verify that favicon suggestions work without recreating the folder as "/." when Azure modules are enabled.
