* fixed issue with specified package versions
zypper.py was doing nothing on state=present, when ALL requestet/checked packages had a specific version stated. This was caused by get_installed_state() being called with an empty package list, which in this case returns information about all ALL installed packages. This lead to an exessive filter list prerun_state, essentially removing all packages that are installed in ANY version on the target system from the request list.
