Fix non-null constraint for script execution

With c34a0e2, validation of job object fields is enabled, so ScriptJob
must not set required fields to empty strings. This commit reverts
b18f193 and (hopefully) fixes this issue not only for UI views, but for
all interactions with scripts.

Fixes: #17923
