[FIXED JENKINS-10044] Restart button does not restart jenkins after plugin upload

Restart button that appears under list of installed plugins after plugin
upload does not restart jenkins when clicked.

More than that, after turning on/off some of installed plugins,
two restart buttons appear (only one of them work) on the page in
question.

Such behaviour should definitely be fixed.
