Rows added to artefact_file_embedded when editing Note not in a page

[Jono M]

When a Note is removed from all pages it is in, any embedded images in the note have their entries removed from the artefact_file_embedded table (since the note can't be shared they aren't needed). However, if you then edit the note from the Notes area and click Save, the embedded image rows are added back to the table.

More specifically
- Add a Note block to a page, and embed an image in the note (using the TinyMCE image button)
- Confirm that a new "textbox" row has been added to the artefact_file_embedded table
- Remove the block from the page. This should remove the artefact_file_embedded row that you saw previously
- Go to "Notes" and edit that note. Click "Save" without changing anything
- Another new "textbox" row will appear in the artefact_file_embedded table

This row isn't necessary, so it shouldn't be added unless the note is in one or more pages.
