Fixed internal errors in RenewalProcessor.

The RenewalProcessor was throwing NumberFormatException if the
renewal request contains an empty serial number. The code has been
modified to check for null and empty string.

If the serial number is unavailable, the code will try to get the
serial number from the client certificate. If that is unavailable
either, the code has been fixed to return a proper message.
