Test MessageManagerSuite, tcp fails unless roscore is running

[GoogleCodeExporter]

1. Open simple_message/test/utest.cpp
2. Enable MessageManagerSuite(tcp) test (currently disabled)
3. Run make test in the package directory.
4. The test will run and complain about a missing core
5. If a core is started the test will pass

The test fails due to a dependency on ros.ok().  If at all possible, this 
function dependency should be removed so that the automated tests can be run 
without a core.

This test has been disabled in the groovy branch.
