Allow to start automatic script manually with empty scriptName

[matthias-ronge]

Is your feature request related to a problem? Please describe.
If an automated task got stuck, you cannot perform the action manually after accepting the task, if the script was not given a name in the workflow editor. Then no link will be displayed.

Describe the solution you'd like
The link shows with a standard text, for example: “Run script”

Describe alternatives you've considered
At the moment, the only way to fix this is to post-assign the title via the database. But I have to restart Tomcat if I manipulate the database.

Additional context
If a script is scheduled to be automatic, you might not have given it a title because, you might have thought, no one will ever see the title anyway.
