Current behavior
When a note with tags is trashed, its tags are still considered under the "Tags" pane. But when we click on those tags the note is not shown.

Expected behavior
Tags of trashed notes not to be shown under the "Tags" pane.
Steps to reproduce
- Create a new note.
- Add some example unique tags to it.
- Delete the note.
- Check the "Tags" pane. You should see the tags you added there.
- Click on them.
