Image not overwritten even if settings seem fine

[Timo-Breumelhof]

I'll test this in a differnet install on a later stage just logging for now:

image definition: Schema:

"Image": { "type": "string", "title": "Image" }

options:

"Image": { "type": "imagex", "uploadhidden": false, "showOverwrite": true, "showCropper": false }

When I select "overwite existing" I do see a message that the file was overwritten but it's not in reality.
