Fixes https://github.com/twentyhq/twenty/issues/12040
When fields are deleted but still used in workflows we do not update
create record action settings.
It breaks all following workflow execution and the user cannot update
the settings anymore.
This PR fixes the bug by filtering on existing fields.
Next step will be to clean settings on field deletion. Adding it to fast
follows.
Also lowering throttle limit because some infinite loops are not
catched.
