[JENKINS-27438] Gerrit Trigger NPE causes folder not to load

Folder containing jobs disappeared. I tried reloading the config from the filesystem option and I still see the same error message. Other team folders are visible and working correctly. Gerrit trigger functionality seems to work as well. I can hit the query and trigger Gerrit Patches link and it works fine.

I see in the logs:

environment

```
Jenkins LTS 1.580.3 (installed standalone using builtin web container)

Cloudbees enterprise plugins installed

Linux RHEL 6.5

Java version "1.7.0_76"

Gerrit Trigger Plugin 2.12.0

```

Start in GerritTrigger.start at GerritTrigger.java:396, using the reported folder-loading stack trace and the Jenkins 1.580.3/Gerrit Trigger Plugin 2.12.0 environment as context. Reproduce loading a folder containing the affected job and verify that the folder remains visible without the NullPointerException while Gerrit trigger functionality continues to work.
