[imp] Save as copy for banners, categories,contacts, newsfeeds

Same fixes as in https://github.com/joomla/joomla-cms/pull/4916 for these components.
For any of these items:
Change the Title/name
Press Save as Copy.
Instead of a figure, the new item will get the new title/name and new alias based on the title/name
