Two possible bugfixes in bb2diaspora.php.

I have found two suspicious parts and tried to correct them. I have no
diaspora enabled hubs and I am also not sure what influence these two
changes will have:
$unset($item['author']) ==> unset($item['author']);
if(cnt) ==> if($cnt)
Before merging can someone with diaspora contacts test this.
