pacman: don't error when a group exists but all packages are ignored

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
before throwing an error.
