Checkmk Werk 14742: Fix combined search for tag groups

ID: 14742 Title: Fix combined search for tag groups Component: Multisite Level: 1 Class: Bug fix Version: 2.2.0i1 If you used "tg:" for tag groups in combined searches, no results were shown, even if the search would match. This feature was broken since at least version 1.6. You can now use combined searches like "s: MY_SERVICE tg: MY_TAG" in the monitoring search and quicksearch again.
