Catch TypeError in indexers if content can not be adapted

Currently plone.app.discussion provides indexers
for IContentish. In these it tries to adapt
the content object to IDiscussion. But an IDiscussion Factory is only
provided for IAnnotatable.
The Criteria are IContentish but not IAnnotatable.
Indexing them fails
