Check_MK Werk 3193: Fixed fake check results for hosts

ID: 3193 Title: Fixed fake check results for hosts Component: Core & Setup Level: 1 Class: Bug Fix Version: 1.2.9i1 Fake check results were handled in a slightly inconsistent way, now their behavior exactly mirrors the processing of "real" check results, making the resulting up/down host states less surprising. Note that submitting a "down" result does not necessarily imply a "down" host state: Depending on the state of its parents, the host in question could go to the "unreachable" state, too.
