Revert a6dac92 to fix repeated group issue 688

Revert "fixed: html script helper, if loading via Asset (in ajax) then only apply onLoad script to the last loaded script."

Reverting commit a6dac9293d5613654cf204a70bc692628528e2bb 
FIXED https://github.com/Fabrik/fabrik/issues/688 , at least for me.

EDIT2: fixed partially. 

1) Here one form works well with 5 repeated groups. You can compare (original_fabrik means the latest code, reverted_fabrik the code with my proposed changes:

http://j25.nurmoja.net.ee/reverted_fabrik/index.php?option=com_fabrik&view=form&Itemid=651&formid=108&rowid=1&listid=108
http://j25.nurmoja.net.ee/original_fabrik/index.php?option=com_fabrik&view=form&Itemid=651&formid=108&rowid=1&listid=108

2) another form agreed to work only with 3 repeated groups. 
http://j25.nurmoja.net.ee/reverted_fabrik/index.php?option=com_fabrik&view=form&Itemid=650&formid=107&rowid=8&listid=107

while with full latest code recognises only one repeated group (like in the example above):
http://j25.nurmoja.net.ee/original_fabrik/index.php?option=com_fabrik&view=form&Itemid=650&formid=107&rowid=8&listid=107

Uncaught TypeError: Cannot call method 'cloneWithIds' of null form-min.js:1
