Extension does not load if Custom File System Provider is present in workspace

[gbrueckl]

I have other extensions installed that implement a Custom File System Provider via the VSCode APIs
It seems like the SQL Database Project extension does not load properly if the current workspace contains an URI of a Custom File System Provider

Steps to Reproduce:

1. add custom file system provider URI to Workspace

{
	"folders": [
		{
			"path": "."
		},
		{
			"uri": "fabric://9bd3314c-7b9a-42d7-8bce-129ef1aaf6e0",
			"name": "My Fabric Workspaces"
		}
	]
}

2. Open the Database Project Tab
   errors out with
   
   (english: "scandir 'c:\documents and settings')

The Fabric Custom File System Provider comes from my PowerBI-VSCode extension but it seems like your extension is not working with Custom File System Providers in general when doing some scans of the file system etc.
I am not referring to 'c:\documents and settings' from my extension so it must be coming from yours
