Similar to issue #6, MapWriteContext.createChildObjectContext() should call _schema.getValueType()

[shoeree]

Hello!

I was attempting to serialize an Avro record containing a "map" with record-type values, and encountered this error:

JsonMappingException: Not an array: <redacted>

... I see that in Issue #6, deserializing the "map" type appears to call getElementType(). In MapWriteContext.java, getElementType() is also called, like so:

@Override
public final AvroWriteContext createChildObjectContext() throws JsonMappingException
{
    _verifyValueWrite();
    AvroWriteContext child = _createObjectContext(_schema.getElementType());
    _data.put(_currentName, child.rawValue());
    return child;
}

Shouldn't this instead use _schema.getValueType()?

Yes, quite probably it should.

Any possibility of a simple unit test? :)
