Extension doesn't index files added via copy-paste

[Shtoyan]

Describe the bug

After copying files (outside of VSCode) into the workspace's directory they do not get indexed - no definitions are exported from them until VSCode restarts. You can't view the parents, super code or anything else.

Enabling-disabling this option, or editing-saving new files to trigger the reindexing doesn't fix the issue.

Perhaps an issue with vscode itself? The server does listen to creation of new files, however none of the events are triggering.
