IT showing inability to resolve versions coming from a profile

Integration test showing #117

[hohwille]

@jtnord thanks for providing this PR with an IT to reveal that something is wrong here.

[INFO] artifact org.codehaus.mojo.flatten-maven-plugin:1.2.0-SNAPSHOT: checking for updates from sonatype-apache

UPDATE: Got the intension from your issue #117 so thanks also for that. Please see my comment also there.

This PR is here so that if someone wants to look at the issue they have a starting point, I am not actively working on this.
