Typo in embedded server documentation

[laurenskvh]

In the "accessing the rethinkdb r object" section the code says:

horizonServer._reql_conn.read().then((reql_conn) => {
    var doc = r.db('horizon').table('users').get(3).run(reql_conn.connection());
});

the read() is wrong as it should say ready()

This is rather confusing as read() looks like a perfectly valid method.
