Investigate property check failure

Don't have time to look at this failure at the moment and haven't seen it before:

[info] BsonCodecInstancesTest:
[info] - BsonCodecInstances should round-trip JSON values *** FAILED ***
[info]   TestFailedException was thrown during property evaluation.
[info]     Message: Right({
