Easyjson test should not interfere with json test

Tests generated standard JSON marshaler/unmarshaler interfaces for easyjson. These will have been picked up by the encoding/json code and thrown off the result for encoding/json.

Better for easyjson test to use its own specific (un)marshaling interfaces only, which easyjson claim are better than the standard ones
