Sorry, that suggestion was based on the package not being in Ubuntu 18.10. I did not realize it is a required package in 18.04.
To fix what was removed by the previous command you can reinstall the missing packages by running:
sudo apt install cheese gnome-control-center gnome-initial-setup gnome-video-effects gstreamer1.0-plugins-good libasound2-plugins libcanberra-pulse libcheese-gtk25 libcheese8 libjack-jackd2-0 pulseaudio pulseaudio-module-bluetooth rhythmbox rhythmbox-plugin-alternative-toolbar rhythmbox-plugins totem totem-plugins ubuntu-desktop
