CodeLens related commands cause exception to be thrown

Prerequisites

• I have written a descriptive issue title.
• I have searched all open and closed issues to ensure it has not already been reported.
• I have read the troubleshooting guide.
• I am sure this issue is with PowerShell Editor Services itself and does not reproduce in a standalone PowerShell instance, and is not an issue with my editor.
• I have verified that I am using the latest version of PowerShell Editor Services.
• If this is a security issue, I have read the security issue reporting guidance.

Summary

In the repository below, I have forked @TylerLeonhardt's old Monaco + PSES example, upgraded to the (almost) latest version of all packages, and wrote up how to reproduce the issue in the README.md.

https://github.com/mhintzke/monaco-powershell

Basically, regardless of OS (Windows or Unix) when the editor detects that the contents contains a basic function, e.g.

function Verb-Noun {

}

Then Monaco Client sends some commands such as textDocument/codeLens and codeLens/resolve. Both of which cause an exception to be thrown here

https://github.com/PowerShell/PowerShellEditorServices/blob/41fce39f491d5d351b4ac5864e89857ec070e107/src/PowerShellEditorServices/Services/Workspace/WorkspaceService.cs#L144

This is all using very basic configuration of the Monaco Editor and a model URI of inmemory://model.ps1. Basically when these commands are handled by PSES, they attempt to open the file at the uri above, but somehow along the way to the function above, gets translated into an "empty" string.

Because we are working with inmemory models here, I feel like we should just not even attempt to perform a File System read at all. I'm not 100% what the intended function of these commands are, but they might be not applicable in the scenario where we use inmemory models. Please correct me if I am wrong.

Reproduce el problema usando el fork de monaco-powershell y su README.md, con una URI inmemory://model.ps1 y una función básica de PowerShell. Empieza en src/PowerShellEditorServices/Services/Workspace/WorkspaceService.cs alrededor de la línea 144 y sigue las solicitudes textDocument/codeLens y codeLens/resolve. El trabajo estará terminado cuando estas solicitudes ya no lancen una excepción para modelos en memoria.
