Retag with old tag name, doesn't show on tag list

If I rename an existing tag, then create a new note with the original tag, then the note gets the tag, but the tag doesn't appear on the tag list.

**Steps to Reproduce:**
1. Create a new note with tag 'tag1' => 'tag1' appears on the tag list on the left
1. Rename 'tag1' to 'tag2' on the left => 'tag2' (but not 'tag1') now appears on the tag list on the left
1. Create a second new note with tag 'tag1' => Tag 'tag1' does not appear on the list on the left, though the second new note does retain the tag even on restart

**Workaround**
1. (same as step to reproduce) Create a new note with tag 'tag1' => 'tag1' appears on the tag list on the left
1. (same as step to reproduce) Rename 'tag1' to 'tag2' on the left => 'tag2' (but not 'tag1') now appears on the tag list on the left
1. Create the second new note with tag 'tag3' => 'tag2' and 'tag3' both appear on the list on the left
1. Rename 'tag3' to 'tag1' on the list on the list on the left

Reproduce the rename-and-reuse sequence in the macOS app, focusing on tag creation, tag renaming, and the tag list on the left. The issue is done when creating a note with the original tag makes that tag appear in the list and remain visible after restart.
