correct 2 small bugs

[BertrandThelen]

• SSL tests were failing due to qCritical abort in case of certificate error because the for loop expectation was never met by the 2 errors at the same time
• Http parse error disconnected the signal but did not closed the socket, leaving the client hanging (tested with curl to force a space in the query parameters).
  Returning a 400 Bad Request could be good but I do not know the full implication that this change could have to the code flow.

Hi @msvetkin

Finally managed to get everything set up correctly for gerrit. So the pull request has been sent there.
Don't know if I can/must delete this one?

I happened to come across this pull request, and I wondered if the or in the logic should be changed into an and, since we're inverting the logic in the original code. Both there error type and the associated error certificate in the expected should match the actual error.
