Category parent relations break if parent name is updated

[GoogleCodeExporter]

If the parent category's name is updated, the category panel updates the parent 
assigned of each category types. If two category types share a category name, 
the other category type's parent relations break when the name is changed in 
the other.

To reproduce:

1. Create 'cat-original' category to both Article and Link categories.
2. Create few dummy categories to both and assign them as the children of 
'cat-original'.
3. Rename 'cat-original' of Article categories to 'cat-new'.
4. Check the database. You will see that all instances of 'cat-original' in 
parent column have been updated.
