Configure job UI erases config values

[Lorquas]

Description: Every time you go to the Configure part of a job, all the configuration for jms-messaging things are blanked out. If you click save, you erased your config.

Reproducibility: Always Versions: jms-messaging 1.1.6 tested on jenkins 2.150.2 and 2.121.3

Steps to reproduce:

1. Obtain a jenkins (I'm using FROM jenkins/jenkins:lts in my Dockerfile)
2. Install jms-messaging:latest
3. Login to that jenkins as admin, and go to Manage Jenkins > Configure > JMS Messaging Providers > add your favourite provider
4. Go to the jenkins top level > New Item > give it a name > Freestyle project > OK
5. Configure this job with: Build (or Post-build Actions) > Add Build Step (or action) > CI Notifier (or CI Subscriber) > Configure the CI action with values.
6. Click Save
7. Click Configure on the job again

Results:

• all configuration values have been blanked out for this plugin
• the config.xml for the job retains the old values (expected)
• if you click save/apply again it will blank out the values in the config.xml

Expected Results: The Config UI shows you the saved values in the config.xml, like all the other plugins.

Additional info: Creating the job with job DSL/JJB could also replace steps 4-5
