Using saved information in Edge leads to unvalid HTTP-request

[KS-DR]

Current Behavior

When using saved information to fill out a HTML form quickly, Edge will send "" instead of NULL for some request parameters, making the request unvalid in some cases.

Steps to Reproduce

1. Create a component with only a name and a version (CPE input field is empty)
2. Create the same component again, until Edge will suggest to fill out the form for you with saved information
3. Note that the CPE input field is still empty, as for all requests before (no whitespace)
4. Get HTTP status 400 (Reason for that is, that "" was send as CPE instead of NULL)

Expected Behavior

DT should also accept "" being send by the browser as value instead of NULL.
