mod_http_index: Hide http apps that haven't set a title by default This setting was meant to default to this but by some mistake defaulted to true. Apps that haven't set a title might not be meant to be user facing, so hiding them makes sense.

This module discards typing notifications sent to a bare host JID,
preventing error replies to be sent. These errors are harmless but can
be annoying sometimes if your client shows them prominently.
