UAT deployments don't reflect the latest pushes to a pull request

[Xiol]

What is the issue?

When further pushes are made against a pull request, any existing UAT deployment isn't updated to reflect the latest changes.

Steps To Reproduce

Steps to reproduce the behavior:

1. Open a pull request with changes.
2. Wait for UAT deployment to complete.
3. Push additional changes to the PR
4. Changes are never deployed to UAT

Expected behaviour

UAT should reflect the PR with additional pushes.

Possible fixes

Rollout restart the deployment if pods already exist?
