tag-autocomplete suggests tags for deleted files (to verify)

[ctwrs]

So one user on discord had this situation where they deleted all wildcards and started chiselling their own. Valid use case. They complained that tag-autocomplete still suggested old tags to them. Not sure if that's the case. I think the index of tags is built on each web-ui start in the install extension step. Not sure now and too tired to check.

ToDo later.
