Title: Fix order number generation

And add a scenario to cover it.
Haven't tested the scenario because I have issue running behat here:

$ bin/behat
[Behat\Testwork\ServiceContainer\Exception\ExtensionInitializationException
`Behat\MinkExtension\Extension` extension file or class could not be located

I have updated vendors, do you guys have the same error?
