`ci_environment_status` endpoint could return a wrong deployment.
Problem
As we don't specify ordering of deployments for MR widget, there is a low chance that it shows a wrong deployment on UI.
Proposal
Return the latest deployment in ci_environment_status
endpoint
Deployment.where(environment: environment).find_by_sha(sha)
should be Deployment.where(environment: environment).order(id: :desc).find_by_sha(sha)
