test_walk_versions() and test_mysql_innodb() are getting the same failure in test_migrations.py.

I'm also seeing these failures on stable/mitaka.

    Tests: Don't attempt connection for Coho driver init

    This test is unreliable because it tries to actually
    connect to the network, and test for failure.

    Rather than trying to actually make a connection,
    just throw an error.
