The MUTABLE_IMAGE_RUDDER variables was using the DOCKER_VERSION instead of MUTABLE_VERSION
```
MUTABLE_IMAGE        := ${DOCKER_REGISTRY}/${IMAGE_PREFIX}/${SHORT_NAME}:${MUTABLE_VERSION}
MUTABLE_IMAGE_RUDDER := ${DOCKER_REGISTRY}/${IMAGE_PREFIX}/${SHORT_NAME_RUDDER}:${DOCKER_VERSION}
```

Fixed referencing the wrong env variable if SHA sum doesn't match.
