NVidia proprietary drivers were not installed

Not sure if that's a bug or a feature, but per test case http://iso.qa.ubuntu.com/qatracker/milestones/437/builds/255601/testcases/1718 the Nvidia proprietary drivers should be unconditionally installed, so that's either a bug on the installer or on the test case itself.

My device (Acer Aspire A515-52G-57NL) is equipped with an Intel i5-8265U processor (UHD Graphics 620) with a Nvidia GeForce MX130 GPU. I expected that by checking the box "Install third-party software..." as instructed in step 6, I'd get the Nvidia driver installed, but that didn't happen in any of the two installation attempts I made. The system booted, enrolling MOK was successful, but there was only Mesa Intel graphics driver, thus the commands `nvidia-smi` and `nvidia-settings` could not run, suggesting a failure on steps 25 and 26 of the test case.

By manually installing `nvidia-utils-515` and `nvidia-settings` I could achieve the results expected in steps 25 and 26, but that required me (the user) enabling network and explicitly installing the required packages.

I wonder if the fact that the intel device is capable of displaying full graphics lead to the choice of skipping the Nvidia driver.
