[BUGFIX] Wrong url for frontend editing popup

Since Forge issue #66052 frontend editing with feedit is not working anymore.
This is because the URL's for modules have become absolute and feedit is adding
the 'typo3' directory name in front of the module url.

This patch removes the 'typo3' directory
