Ignore org.mockito:mockito-core:2.23.0

This version brings new classpath problems:

  [WARNING] Rule 3: org.apache.maven.plugins.enforcer.BanDuplicateClasses failed with message:
  No Duplicate Classes Allowed!
  - For duplicate transitive dependencies, add dependency exclusions.
  - For duplications between direct dependencies, resolve or add
    ignored classes to this rule's configuration.

    Found in:
      net.bytebuddy:byte-buddy:jar:1.9.0:test
      net.bytebuddy:byte-buddy-agent:jar:1.9.0:test
    Duplicate classes:
      module-info.class

Can probably be addressed with an addition to the
allowedDuplicateClasses property, but no urgent
need to upgrade mockito, so let's punt for now.
