Notebook file not updated by generate

[stephane-caron]

My understanding of what gepetuto does may be wrong. I'm expecting the source notebook files will be re-generated when e.g. a snippet script changes.

Reproduction steps

• Create a notebook
• Add a cell with %load my_snippet
• Run gepetuto -vvca all
  • The notebook file is updated, the %load line becomes #%load and the content is added properly.
• Modify my_snippet
• Run gepetuto -vvca all

Expected outcome

The notebook file is updated.

Current outcome

The notebook file stays as it is, the cell starting with #%load has not been updated.
