ITs should not check for SHA1/MD5

[kwin]

Some ITs check for SHA1/MD5 being generated in the local repo. That is not a good test as those are being generated by maven-install-plugin prior to version 3.0.0-M1 (https://issues.apache.org/jira/browse/MINSTALL-143). You should either explicitly disable checksum creation via https://maven.apache.org/components/plugins-archives/maven-install-plugin-2.5.2/install-mojo.html#createChecksum or rely on other checksums in the IT!

Update: Even disabling the checksum creation does not work, as the maven-resolver-plugin will generate it anyways (compare with apache/maven-artifact-transfer#16).
