Uninstall fix for named-pkcs11
    
    Sometimes named-pkcs11 is not being stopped or reloaded during
    uninstall and it causes a lot of problems while testing, for example,
    backup and restore tests are failing because of ipa-server-install
    fails on checking DNS step.
    
    Fixes backup/restore tests runs. Maybe something else.
