Fix pax exam issue

auto-release is all of a sudden seeing these failure for the
ToasterTest:

I was able to repro locally by removing the
org.ops4j.pax.tipi.hamcrest.junit and org.ops4j.pax.tipi.hamcrest.core artifacts
from ny local .m2 repo. Adding the dependencies to the mdsal-it-base pom
causes them to be downloaded and fixes the issue. However it's a mystery why
this issue all of a sudden popped up and why it seems we have to explicitly
reference those depnedencies.
