Use find_resource() instead of get() in _prep_server_detail()

There is such a comment in test_server.py:

    # Call .get() to retrieve all of the server information
    # as findall(name=blah) and REST /details are not the same
    # and do not return flavor and image information.

This is an out of date comment. There is no function named
findall() in OSC now. So use find_resource() instead of get(),
and remove this comment.
