Bug 29782: Fix handling records without title or content

Test plan:
Save a new record with only a title in the non-default tab (english).
Check if you see it on the list. Edit.
Save a new record without title but only content in non-default lang.
Check if you see it.
Do the same 2 edits on the default tab only. Verify too.
