Drop host name resolution failure test

This test seems to be causing us problems, some build systems will
correctly fail the resolution and the test passes like we want it to,
but others incorrectly resolve the address due to misconfiguration
of the local name service, causing the test to fail, and the Maven
build to abort.

Just drop the test.  Its more effort to maintain than it is worth
to verify that we caught and rethrew this one UnknownHostException
like we want.  I've already had 2 bugs opened over this test case
failing for others who are trying to build from source.
