Combining multiple channels fails when resolve-if-no-stream: maven-release is used

[TomasHofman]

Trying to provision with following channels:

---
schemaVersion: "2.0.0"
name: "SSHD open channel"
repositories:
  - id: "deployment-repo"
    url: "file:/home/thofman/Projects/mina-sshd/repo"
manifest:
  url: "file:/home/thofman/prospero/empty-manifest.yaml"
resolve-if-no-stream: maven-release
---
schemaVersion: 2.0.0
name: "EAP 8 Channel"
manifest:
  maven:
    groupId: "org.jboss.eap.channels"
    artifactId: "eap-8.0"
repositories:
  - id: "mrrc"
    url: "https://maven.repository.redhat.com/ga/"
resolve-if-no-stream: none

(For testing purposes the first channel repo can probably be an empty dir, and the first channel manifest URL has to reference an empty manifest.)

Tryting to provision with java -jar prospero-cli-1.1.6.Final-redhat-00001-shaded.jar install --profile eap-8.0 --dir eaptest-release --channel channels.yaml I get an error:

ERROR: No versioning information found in metadata.

If fails when the first channel (SSHD channel) is trying to resolve maven metadata for org.jboss.eap:wildfly-ee-galleon-pack. It should be OK that the first channel is not able to resolve it - it would be resolved by the "EAP channel" - and this resolution failure should be silently ignored.
