Operate against the boxen mysql instance and don't attempt to create existing databases

Previously operations were going against the default mysql port 3306. This changes that to use the boxen mysql port and prevents attempting to create existing databases. Also, grants needed permission levels for operating against this mysql instance. Weird problem with the db spec though. When using the `${mysql::config::port}` var, the spec fails but when I explicitly set to 13306 it works. So I'm not sure what's up there but this gets the spec passing.
