fix updating the styles to 5.3

If `Style::$imagePath` is empty, it resulted in copying the shole WSC-folder into a style-asset-folder - and doing this until we reache the timeout limits.
Including `global.php` ended up in trying to define the option-constants (especially the fixed-value-options like `MODULE_ATTACHMENTS`) again while they are already defined - which causes a Fatal Error-Message.
