This feature was implemented with MGNLDIFF-70. But there is problem with multisite environment.

DiffLink.getLocales() always return locales from default site because storageNode path start with "/activation/..." and not with actual site prefix.

Instead getOriginalContent() should be used to aquire the proper node.

To Reproduce:

• In demo-features site, enable i18n
• Add an additional locale, fr. (This is important because the problem only shows up when the locale is something that is not present in Default site definition.)
• Edit Page /demo-features/content-templates/article, Edit the title of the "Page Header" component.
  • Make the english version 'Article EN 1', make the french version 'Article FR 1'.
• Publish the change & Go to the Inbox and Approve the workitem.
• Edit the page again
  • Make the english version 'Article EN 2'. make the french version 'Article FR 2'.
• Publish the change.
• Go to the inbox, double click on the workitem, you'll see links at the bottom to Compare for each language.
• You'll see that English works correctly, but that French shows the English changes too!
