Drone downgrade does not honor `-project` flag

[jimsheldon]

Steps to reproduce

1. Create example.yml

   kind: pipeline
   name: example
   type: docker
   
   steps:
   - name: echo
    image: busybox
    commands: [echo hello]

2. Run go-convert

   $ go-convert drone -downgrade -project example example.yml
   pipeline:
    identifier: default
    name: default
    orgIdentifier: default
    projectIdentifier: default
    properties:
      ci:
        codebase:
          build: <+input>
    stages:
    - stage:
        identifier: example
        name: example
        spec:
          cloneCodebase: true
          execution:
            steps:
            - step:
                identifier: echo
                name: echo
                spec:
                  command: echo hello
                  image: busybox
                timeout: ""
                type: Run
          platform:
            arch: Amd64
            os: Linux
          runtime:
            spec: {}
            type: Cloud
        type: CI

   Notice that projectIdentifier is default when it should be example.
