Fix new problem with LT-11746: Make Preview aware of publication

[jtmaxwell3]

This fixes a new problem with https://jira.sil.org/browse/LT-11746: Lexical relations shouldn't be shown if they are not in the current publication. The solution was to pass in a DictionaryPublicationDecorator like the one in XhtmlDocView.cs.

Src/xWorks/XhtmlRecordDocView.cs line 170 at r1 (raw file):

				var configuration = new DictionaryConfigurationModel(configurationFile, Cache);
				PublicationDecorator.Refresh();
				var xhtmlPath = LcmXhtmlGenerator.SavePreviewHtmlWithStyles(new [] { cmo.Hvo }, Clerk, PublicationDecorator, configuration, m_propertyTable);

Did you check and see if there are any visual changes after this beyond the current bug fix?
We explicitly passed null here before and I think we have some code that expected that for the single entry preview styling. That was probably overloading the parameter, so the fix isn't to undo this but to make that single entry view explicit.
