QCoapReply: add test for a chunked read 

QCoapReply is a QIODevice, but it was not obvious if readData() is
implemented properly, or if it also needed to update pos().

This patch adds a unit test that checks a chunked read from the reply.
The test passes, so nothing needs to be fixed in the implementation.
