Fix json parsing exceptions obscuring server errors (#1605)

Browse source 
I got a 413 (Rate limit exceeded) error from the server while fetching prekeys.
The client tried to parse the response as json since we expect json from the
prekey endpoint, which threw an exception because the response was not json.
This change prevents us from treating the response as json unless it has the
Content-Type header set accordingly.

If for some reason, the client and server disagree on whether the response
should be or is json, we'll default to treating it as text.
