[JENKINS-73161] File parameters are not retained across Jenkins restarts

[jenkins-infra-bot]

Steps to reproduce

1. Create a freestyle job
2. Configure it to have a file parameter
3. Go to /job/…/build?delay=100sec (add to delay), specify a file and click Build Now
4. Wait a few seconds to persist the queue (just in case)
5. Restart Jenkins
6. Wait until the build is started

Expected results

The build starts and successfully picks up the file parameter, behaving as if there was no restart while the build was queued

Actual results

The build fails with:

Running as SYSTEM
Building in workspace /var/jenkins_home/workspace/fs
FATAL: Cannot invoke "org.apache.commons.fileupload.FileItem.getName()" because "this.this$0.file" is null
java.lang.NullPointerException: Cannot invoke "org.apache.commons.fileupload.FileItem.getName()" because "this.this$0.file" is null
	at hudson.model.FileParameterValue$1.setUp(FileParameterValue.java:159)
	at hudson.model.Build$BuildExecution.doRun(Build.java:158)
	at hudson.model.AbstractBuild$AbstractBuildExecution.run(AbstractBuild.java:526)

	at hudson.model.ResourceController.execute(ResourceController.java:101)
	at hudson.model.Executor.run(Executor.java:442)
Finished: FAILURE 

Notes

May be a regression in 1.494 due to 4dde24e according to #9260 (comment)

  Just noting that a stashedFile parameter from file-parameter plugin also doesn't survive a Jenkins restart while it is in the queue

  mawinter69 better report that in the plugin (currently there is a test for the Base64 version of this scenario only).
