Description of problem:
Revert bundle to a version fails
Version-Release number of selected component (if applicable):
jon-server-2.4.0.GA_QA Build# 51
Steps to Reproduce:
1. Go to Administration -> Content -> Bundle
2. Upload and deploy a bundle version say version 1
3. Upgrade to bundle version 2.
4. Navigate to 'Destination' tab for bundle version 2
5. Click on 'Revert' button.
Revert Deployment confirmation and Provide Revert information both the pages are blank and when clicked on Next the revert fails.
The page should display the revert deployment confirmation and provide revert information page with some values to input.
This to me looks like a manifestation of Bug 612115
fix commit: 91c9d1fb7849b9966f60a2cdeb8bca1903e3389c
The only way I could reproduce the above situation was to click Revert when if fact the destination had only 1 deployment. Meaning, in the destination view page there is only one deployment in the list. In this situation the live deployment is the *only* deployment and there is nothing to revert to.
I've improved the revert wizard to better handle this situation and display a (hopefully) useful message. And it will not let the user continue past the first step.
Verified on latest jon 2.4.0.GA_QA build#53
If the destination view page has only one deployment in the list and user clicks 'Revert' button, below messages is displayed in the wizard:
Live deployment [BundleDeployment[id=10031, name=Deployment  of Version [1.0] to [deployversion1]]] can not be reverted. There is no prior deployment for the destination [BundleDestination[id=10031, bundle=example, group=linux1, name=deployversion1]]
Deployed version2 of the bundle to same destination. Navigated to the destination tab and clicked on 'Revert' button. The bundle is reverted successfully to previous version.
