RecordEvolutionTest

during investigation upgrading Avro to 1.9+, the test was failing. the code has enforced the rule from the specification that when a default value is specified for a record field whose type is a union, the type of the default value must match the first element of the union. Thus, for unions containing "null", the "null" is usually listed first, since the default value of such unions is typically null.

it was part of specification in 1.8 already https://avro.apache.org/docs/1.8.0/spec.html#Unions , just not enforced in the codebase.

relates to #167
