Merge pull request #566 from Icinga:fix/do_not_continue_testing_for_directories_in_case_agent_not_installed

Fix: Useless testing for directories if agent is not installed

Fixes useless testing and printing of error messages, in case the Icinga Agent is not installed during installation and Icinga for Windows printing plenty of errors, because the ACL checks cannot be completed.
