Ok so I reset the module, and put the removed code back, hooked it to the 2 positions available and got it to eventually run.

Tried updating the test site and after copying the files and upgrading the database I get the following error.

CRITICAL - ErrorHandler - /home/********/public_html/var/cache/prod/FrontContainer.php line 2216 - Symfony\Component\DependencyInjection\Exception\InvalidArgumentException: The parameter "prestashop.installed_modules" must be defined.

then loading the B.O I get

An exception has been thrown during the rendering of a template ("An exception occurred while executing a query: SQLSTATE[42S22]: Column not found: 1054 Unknown column 't0.type' in 'SELECT'").

and the F.O shows this

[PrestaShopException]

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'theme_name' in 'WHERE'
at line 151 in file classes/db/DbPDO.php

146.     protected function _query($sql)
147.     {
148.         try {
149.             return $this->link->query($sql);
150.         } catch (PDOException $exception) {
151.             throw new PrestaShopException($exception->getMessage(), (int) $exception->getCode(), $exception);
152.         }
153.     }
154. 
155.     /**
156.      * Returns the next row from the result set.

I tried the update twice. 

I had the "Disable overrides" checked and tried with and withouth "disable non native modules" checked.
