c-hyper: handle body on HYPER_TASK_EMPTY

Some of the time, we get a HYPER_TASK_EMPTY response before the status
line, headers, and body have been read. Previously, that would cause us
to poll again, leading to a 1 second timeout.

The HYPER_TASK_EMPTY docs say:

   The value of this task is null (does not imply an error).

So, if we receive a HYPER_TASK_EMPTY, continue on with processing the
response.
