Bug 205709 Translation table is missed when report design is flattened
It happens when a report design with a localization property file and some library (otherwise it's not flattened!) is executed. Such report document has no transaltion table and then can not be localized. The problem is in org.eclipse.birt.report.model.util.ReportDesignSerializer#visitReportDesign which does not copy the translation table from ReportDesignSerializer#sourceDesign to ReportDesignSerializer#targetDesign.
