BibFormat: removes 'No fulltext' message

* Removes 'No fulltext' message as the default message of the full-text
  mini panel for records that do not have any file attached, because it
  was confusing for users e.g. for Books and other such material where
  the full text is not expected.  Nothing is displayed by default instead.
