Fixes: #17923, #17921 - Fix non-null constraint for script execution (#17932)

* 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

* Fix name of recurring jobs

For recurring jobs, the name must be passed to the next job object when
the job is rescheduled.
