No more possible to compare published and to deploy status

[exalate-issue-sync]

Describe the bug :

If we make changes to an API definition and not deploy the API, we expect to see the TO_DEPLOY button in the history section. This is so that we can compare the effects of what would happen if we chose to deploy the API vs before deployment. Now if we reload the page, we get a bug in the UI and we are unable to view the TO_DEPLOY anymore. In some cases logging out and in again helped, but in some other test I wasn't able to view the TO_DEPLOY again. The bug is different in different versions of APIM, in version 4, UI bug is completely different as we cannot see the TO_DEPLOY at all, but all UI bugs affect the TO_DEPLOY.

To Reproduce :

Steps to reproduce the behaviour: Replication steps for 3.20.26/27

1. Create a simple Echo API
2. Make changes to the API defintion
3. Do not deploy the API
4. Go to history
5. If you see the TO_DEPLOY it is fine, now reload the page
6. You should be able to see the UI bug now.

Desktop :

• Environment: One scenario in 3.20.26 & 3.20.27, another in 4.2.1
• Browser: Chrome and Firefox
