[JENKINS-31678] NullPointerException when using GitPublisher in release post build actions

Configure a job to use the Jenkins release plugin and use the Git publisher as release step after a successful release build. Tick the checkbox "Push only If Build Succeeds". Then a release build failes with the following NullPointerException:

FATAL: null

java.lang.NullPointerException

at hudson.plugins.git.GitPublisher.perform(GitPublisher.java:203)

at hudson.plugins.release.ReleaseWrapper.executeBuildSteps(ReleaseWrapper.java:423)

at hudson.plugins.release.ReleaseWrapper.access$300(ReleaseWrapper.java:99)

at hudson.plugins.release.ReleaseWrapper$4.tearDown(ReleaseWrapper.java:370)

at hudson.model.Build$BuildExecution.doRun(Build.java:173)

at hudson.model.AbstractBuild$AbstractBuildExecution.run(AbstractBuild.java:534)

at hudson.model.FreeStyleBuild.run(FreeStyleBuild.java:43)

at hudson.model.ResourceController.execute(ResourceController.java:98)

at hudson.model.Executor.run(Executor.java:410)

This is caused by the null derefenced buildResult of AbstractBuild.getResult().
