(#3489) Explicitly set repository optimizations

The WireMock.Net Server is setup to reply to requests made when _NOT_
using repository optimizations, so let's make sure that we are using
that configuration explicitly.  It was found that when running all the
integration tests together, this value could be set to true elsewhere,
which then causes tests here to fail. This is far from ideal, and the
Configuration should have been reset when starting this scenario
but for now, let's explicitly set to false, as this is what we know the
WireMock.Net server will respond with.
