Checkmk Werk 13374: Fix wrong converting of disabled service rules with negate on update

ID: 13374 Title: Fix wrong converting of disabled service rules with negate on update Component: Setup Level: 1 Class: Bug fix Version: 2.1.0i1 Since version 2.0.0, if disabled service rules with negated service condition were used, these rules were wrongly converted with the next 2.0.0p update. The negate condition was empty after updating, leading to missfunctional rules. This also happens while updating from 1.6.0 to 2.0.0. If you used such rules, you have to set the service condition with negate again.
