Problems when a symlink to a template is broken

[fkusche]

This is a follow up to my "question" in the vscode marketplace.

I am using this version of vscode:

Version: 1.40.0 (user setup)
Commit: 86405ea23e3937316009fc27c9361deee66ffbf5
Datum: 2019-11-06T17:02:13.381Z
Electron: 6.1.2
Chrome: 76.0.3809.146
Node.js: 12.4.0
V8: 7.6.303.31-electron.0
Betriebssystem: Windows_NT x64 10.0.18362
(Should be the normal Windows version)

I have my templates under version control, so I create a symlink like this from my vscode-settings to my versioned templates:
New-Item -Force -Path ( Join-Path $env:APPDATA "Code\User\globalStorage\3axap4ehko.file-templates-manager\Python.py" ) -ItemType SymbolicLink -Value C:\own\etc\code\FileTemplates\Python.py | Out-Null

This works well, unless I delete (or rename) the destination of the symlink. Then, the "Templates" explorer will be empty, when I start vscode and actions like the refresh button show error messages in the lower right.
