Check_MK Werk 4431: Fixed enabling/disabling of notifications/active checks/passive checks

ID: 4431 Title: Fixed enabling/disabling of notifications/active checks/passive checks Component: Core & setup Level: 1 Class: Bug fix Version: 1.5.0i1 Changing various flags in an ad-hoc (i.e. non-rule-based) manner did not work correctly: Changing a flag to a value different from the configurated one worked, but trying to change it back to its configurated value had no effect. This affected the various Enable/Disable buttons on the host/service details pages plus the corresponding Livestatus commands (ENABLE_HOST_CHECK etc.). Note that 1.2.8 versions and earlier are were not affected by this bug.
