The assets for elfinder.min.js are giving 404 when using a different asset_path

Describe the bug I have my asset_path configured to a different folder now with the recent changes: https://github.com/helios-ag/FMElfinderBundle/pull/493 i breaks it probably was already broke before this fix. Some more context: https://github.com/helios-ag/FMElfinderBundle/pull/493/files#r1162540304

To Reproduce Have a asset_path defined to different folder then the default and check you get 404 when loading the assets.

Also can confirm that /img/volume_icon_ftp.png is also not loading for me
