    package_manager.py: Avoid installing an empty package list
    
    It is possible in an attempt only install, that everything listed is not
    available to be installed.  This will have the effect of clearing the
    package list.  However, we only check for an empty package list at
    the beginning of the function.  We need to also check before running the
    install, otherwise we can fail due to 'error: no package(s) given".
