[TYPO3-mvc] Updating a list empties it!

Hi,

OK, here's the point!

Structure of MM table for blog_example is as such:

uid_local
uid_foreign
sorting
sorting_foreign

whereas my structure is this one:

uid
pid
uid_local
uid_foreign
tablenames
sorting
sorting_foreign
tstamp
crdate
hidden

Don't know why but I guess this is related to some automatically 
generated code from kickstarter a long time ago. My TCA then looks like 
that:

'MM_match_fields' => array(
	'tablenames' => 'fe_users'
),

and as the tablenames column is not populated, the relations are lost!

I just removed this condition and this suddenly works as expected. I 
guess I could now easily get rid of unneeded columns too.
