This PR fix bug Bug 1874154: Model Overview: On choosing a specific feature cohort and trying to choose feature cohort again - dropdown has all cohorts selected

Description

Bug repro steps:

1. select OS, job title under feature cohorts
2. Click on choose cohorts
3. select feature cohorts
4. deselect all, select one from list and confirm
5. click on choose cohorts
6. all feature cohorts are selected again by default

Root cause:
The code try to compare if the selected feature changed or if the selected feature cohorts changed, then it set the selected cohort value with the whole feature cohorts list. Per my understanding, we only need to set the selected cohort with whole feature cohort when user select a new feature.
Fix:
For selected feature cohorts, only update to the original whole feature cohort list when feature changed
