add test for #82

There's a problem when inserting values containing emojis in unparameterized queries. It appears that the orientdb sql parser cannot handle them and is bailing out, whereas this does not occur when using bound parameters (recommended usage). We're using a slightly older version of the orientdb *binary protocol* (not database version) and I'm going to upgrade us to the latest version before reporting this as a bug there.

I'm going to pretend that this fixes #82 because it's a problem with orientdb and not oriento.
