[JENKINS-38270] Conditional build step config discarded when upgrading to plugin 1.3.5

We upgraded conditional-buildstep plugin from 1.3.3 to 1.3.5 and noticed that all the conditional build steps vanished from the job configuration.

We restored the job configuration from backups but even when the 1.3.3 XML nodes are present in the config.xml the build steps are neither visible in the web-UI nor executed during the build.
