No alias generating by act=override on Multiple Product Edit

[michelbalzer]

I wanted to let Isotope (2.3.4 on Contao 3.5.9) write new aliases for multiple marked products (in my case all) but they weren't generated when I left the Alias field empty on the override act (as I would do if I want to do exactly this in the Page Structure).

Steps to reproduce:

1. Go to Product Management
2. Click „Edit Multiple“
3. Mark the designated Products
4. Click button „Override“
5. Choose „Alias“ from the field list
6. Click button „Continue“
7. Don't enter any text in the alias field
8. Click Button „Save and Close“
9. Edit one of the Products you just had overwritten
10. Wonder that there is no Alias based on the product name but rather the product ID

I don't really have a real clue, but has it something to do with

core/system/modules/isotope/library/Isotope/Backend/Product/Alias.php

Line 26 in 51a8cfb

public function save($varValue, \DataContainer $dc)

, as „Save and Close“ delivers saveNclose and not just save?
