[Avro] JsonInclude.Include.NON_NULL does not use default values

In the following example, I'd expect that the default value defined for the property `map` would be used. Instead, `null` is passed, which produces an error as null is not allowed for this field.

Schema
```json
{"type": "map", "values": "string", "default": []}
```

POJO
```java
class Foo {
@JsonProperty("map")
@JsonInclude(JsonInclude.Include.NON_EMPTY)
Map getMap();
}
```

Error
```
com.fasterxml.jackson.databind.JsonMappingException: null of map in field map of Foo
```
