Missing field on required.

[Deiru2k]

If a required validation falls on some field, the error object does not represent the exact field name that is missing from input, only providing it as a part of a message, which forces me to use a rather messy code to extract it from error message.
path and schema_path both set to empty dequeue object, and absolute_path is missing as an attribute entirely.

Hey, yup, this is #119. There's some discussion over there but mostly it's just waiting for a patch, would be great if you're interested :)
