Pressing Cancel during Ubuntu 16.04.3 Server installation after OEM install and after running oem-config-prepare aborts the installation.

The behaviour is different from a regular Ubuntu 16.04.3 Server installation (without OEM) where the option at the bottom is "Go Back" which will send you back to steps menu. In the OEM mode, the options are "Ok" and "Cancel" and pressing Cancel will break the installation.

Reproducer steps:

1.Download Ubuntu Server 16.04.3 from https://www.ubuntu.com/download/server
2.Boot VM with ubuntu-16.04.3-server-amd64.iso
3.Highlight "Install Ubuntu Server" and press F4 and choose "OEM install (for manufacturers)" and press Enter on "Install Ubuntu Server"
4.Accept all defaults and choose a password
5.Reboot at the end of the installation
6.Enter login prompt (username:oem and password you set)
7.sudo oem-config-prepare
8.Reboot
9.In "Select a language" screen, press Cancel
10.Installation aborts and OEM-config.service fails to start and hangs forever. The exact error message is: "Failed to start End-user configuration after initial OEM installation"
