Is it tested? How?

1. Deploy Eclipse Che, and set the following in the Che CR to test out this PR:

spec:
  components:
    dashboard:
      deployment:
        containers:
          - image: quay.io/dkwon17/che-dashboard:fixRemotesUrlParam

2. Access the following url to start a new workspace:

{che-host}/#https://github.com/dkwon17/quarkus-api-example?remotes={https://github.com/che-incubator/quarkus-api-example}

and verify that the resulting dev workspace has the following:

          checkoutFrom:
            remote: origin
          remotes:
            origin: 'https://github.com/che-incubator/quarkus-api-example'
        name: quarkus-api-example

3. Access the following url to start a new workspace:

and verify that the resulting dev workspace has the following:

    projects:
      - git:
          checkoutFrom:
            remote: origin
