[FIX JENKINS-40813] Better message on 'Enable security' option

When an empty Freestyle job config gets submitted in the default configuration of Jenkins 2.35, the data is being saved to the disk *8 times*. All of them happen in this code: https://github.com/jenkinsci/jenkins/blob/master/core/src/main/java/hudson/model/Job.java#L1227-L1246

* setDisplayName
* Project#getBuildWrappersList().rebuild (onModified handler)
* Project#getBuilderList().rebuild (onModified handler)
* Project#getPublisherList().rebuild (onModified handler)
* AbstractProject#makeDisabled
* AbstractProject#setScm
* AbstractProject#triggers.replaceBy
* final save()

There is not so much sense to save partial configurations to the disk due to the risk of data inconsistency there. This change just wraps the config submission section of the job into the BulkChange clause.
