Nice to have: Cancel report button

[gbatiston]

It would be a nice asset to have a "Cancel report" button at the last step of the report's creation. If the user wants to cancel the creation there's no way to do so but going back.

1 - Create a report
2 - Get to the edition step

Expected: A "Cancel report" button for the user to cancel the creation of it.
Obtained: There's no way to cancel the report's creation but to navigate the flow backwards.
