Description

PrimitiveSchema class overrides WriteJson method to handle a shotrcut where primitive type is given as a literal, but in doing so it ignores teh case where there are custom properties attached to it.
This breaks any functionality which relies on the equality of the schema re-parsed from its ToString/WriteJson output, one example being csharp codegen.

Example:

{ "type": "string", "logicalType":"DateTimeInstant", "logicalEncoding":"ISO8601-datetime-offset" }

becomes "type" : "string"
