Fix intrasite links for non-'summary' metadata

Metadata like `MyArticleBanner: ![alt text]({attach}banner.jpg)` would be properly parsed (as defined in `FORMATTED_FIELDS`), but the intrasite links would not be processed.

Only the summary gets its intrasite links processed, has its value is either generated from the content (calling self._update_content at some point) or self._update_content is explicitly called if summary is passed as metadata.

This PR expands the paths as soon as possible in (`Content.__init__`) for metadata defined in `FORMATTED_FIELDS`.
