Merge branch 'fix-retries-on-manual-actions' into 'master'

Fix two small problems on how we handle manual actions

## What does this MR do?
Fixes two small problems in how we handle manual actions:
- On environments page we show a `Play` for the same action that is lately deployed, we should show other actions only
- When we process a pipeline that have only a manual action in a stage, the pipeline will stop being processed.

- Tests
