The problem is on the UI side of things; for both Zeppelin and the CLI.
When I get the result back from Stellar, I was using
`ConversionUtils.convert(value, String.class)` to get me a result that I can
display. `ConversionUtils` just gives you the first item back if you ask it to
convert a list to a String. Oops.---
