Description?	Fix the build of the backlog of files updates, where the deleted files were not a valid absolute path to the unzipped archive of PrestaShop
Type?	bug fix
BC breaks?	Nope
Deprecations?	Nope
Fixed ticket?	Fixes #1552
Sponsor company	@PrestaShopCorp
How to test?	Files to delete are not triggering anymore errors during an update. To reproduce this issue, the root path of the webserver files must be added to the basedir. For instance, this is /var/www/html on a Docker environment, so in the php.ini you would get:

open_basedir = "/var/www/html/:/tmp"
