[BUG]: "Ghost" articles appear when creating new account

[slalaurette]

Brief description of the issue

I had an issue where the main account was duplicated, so I deleted it and created a new one. When prompted to add the default feeds, I said no. But I do have a list with dozens of articles, all of them coming from feeds I had in the main account I deleted.

How to reproduce the bug?

Not sure. I deleted the main account that was appearing twice after making a backup, and created a new main account. I also set a custom icon for it.

What was the expected result?

I expected to have a completely empty article list.

What actually happened?

I got dozens of articles. No folders or feeds listed, just the articles.

Debug log

No log. Does this feature work?

I have observed that adding the "Feed ID" and "Feed" columns to the list brings up different feed IDs for the articles, but the feed name is always empty.
