Merge of PR #483 breaks integration tests

[jensh007]

Since merging the PR integration tests are failing:
See e.g. Run log

I can reproduce the error also when running the tests locally. First analysis:

• It seems that he behavior of ocm push -f --copy-resources has changed

Input is like:

    components:
    ...
        resources:
          - name: image
            type: ociImage
            version: "1.10"
            access:
                type: ociArtifact
                imageReference: gcr.io/google_containers/echoserver:1.10
...

After pushing with the mentioned parameters the remote comp-descr in the oci registry contains in access/imageReferencea URL. Now the host name and path is different after PR-merge.
before: '<host>:<port>/inttest/google_containers/echoserver:1.10'
now: 'gcr.io/google_containers/echoserver:1.10'

The problem is caused by the special scenario you have here.
You do a re-transport into a target environment, which uses a different transport mode than the previous one.
First you do a reference transport and later on a value transport of the very same content.

Unfortunately this collides a little bit with the new detection of identical content, which now controls the transport.
This is very tricky.

I'm working on a solution to handle such cases.
