Currently when attempting to sync a group where all packages are ignored (either by ignorepkg, ignoregroup or --needed) pacman will error with "target not found".

Instead, if a group has no packages, check if the group exists and only throw an error if it does not.

Let's put group_exists in the front-end. We may want to modify it to take usage or other factors into account and I don't want to have to figure out how to fit that into a public API, and it's a lot easier to move it from the front-end to the back-end if we do decide to in the future than the other way around.
