Each roster item is represented as a record in the database. The
username and password of each account is also a record. I think the
general behaviour in the Mnesia tables is to append and overwrite.

 - the already existent roster contacts are overwritten, they are not
duplicated (and any new change is lost)
 - the very new contacts are kept

I remember jabberd14 spool files from very old jabberd version had
problematic XML. The solution was simply to fix the problematic XML
files, and import again. No need to clean the ejabberd database before
importing again.
