It wasn't possible to cancel a purchase order
within the state "Waiting for Approval", despite
the fact the button cancel is displayed.
Clicking on the cancel button just did nothing.
This is now properly working, thanks to the additional
path added by this revision, between the workflow states
`CheckForApproval` and `cancel`.

In the module `purchase_double_validation`,
you can change the limit to require a second approval
in the purchase settings.
If the module was updated, the limit was re-set to
its default value.
