To test, with this patchset applied:
1) From patron accounting page -> Add a manual invoice
2) Under the transaction tab click 'Cancel charge'
3) You should see a modal that gives you the option to type in a note.
4) Type something in and select submit.
5) Ensure the note shows up in the note column.
