Non-JSON transcoders cannot be mixed with requests for document expiry

When performing GetAsync and requesting Expiry using the options, an exception occurs if you are using a non-JSON transcoder, such as the RawBinaryTranscoder. It incorrectly tries to parse the document as JSON. Also, it does so using intermediate dynamic types, which will be less performant than deserializing directly to POCOs.

Unexpected character encountered while parsing value: q. Path ‘’, line 0, position 0.
