Prestashop: 1.7.6.0 Disable override button not working

[glictevo]

Describe the bug
The button to disable overrides is not working properly.

To Reproduce
Steps to reproduce the behavior:

1. Install a fresh PrestaShop
2. Add an override, for example for classes/CMS.php, override the __construct() function and add an echo 'hello'; followed by a die();
3. Delete the class_index in /var/cache/prod/class_index.php
4. Put yes on the disable overrides in the parameters in the back office
5. Go to any CMS page and modify it, the override is executed.
6. Even if i delete all the cache afterward it is still executed

I hope this is enough to reproduce the bug.

Additional information
PrestaShop version: 1.7.6.0
PHP version: 5.6

Hello,

I've made a few researches.
The bug started at 1.7.3.0 (migration of the AdminPerformance page to Symfony, I don't know if it is linked)

However, I tested in 1.7.2.5, overrides are deactivated when switching the button to "Yes", however when deleting the cache by hand or with the "Empty cache" button in AdminPerformance controller, when the cache is regenerated, the bug is present and overrides are not deactivated. Then if switching to "No", save, reswitch to "Yes", save, then everything is fine and overrides are deactivated.
Same for 1.7.1.2 and 1.7.0.6, I haven't tested any version below this one yet.

Hope this can help a little for the moment.
