earseOnUpload flag needs to be set in javascript

Where is it?

[foxriver76]

Information for us internally, @Apollon77 will fix it for JavaScript

[Apollon77]

Current approach would be:

• Set the flag manually in adapters that have generated UIs for admin/web
• Discuss here if it is maybe better to change te default to "if not disabled then always erase" for .admin and/or .www with controller 4.1

[Apollon77]

Decision is to always delete by default, so we ajust is to "do not delete if set to false"
