Deprecate old import.

Bug fixes:
- Fix ``folder_contents`` view incorrectly returning an ``application/json`` response instead of a ``text/html`` response.
[thet]
- Fix issue with ``get_top_site_from_url``, where in some circumstances a ValueError was thrown.
If that happens, just return ``getSite``.
You will only notice, if you have subsites, access them non-VirtualHost-rooted and an error is thrown.
Then folder contents won't be able to navigate up to the root Plone site.
