Backport: CMS7-6596 CMS doesn't handle document translation names with line ends well

We need to backport the changes made in CMS7-6596 to get the right dialog titles in Advanced Search. Without the backport, titles of wizard dialogs in Advanced Search cannot be looked up and the following stacktrace is logged:
