No log messages comming from Elytron - exception handling

Log error messages from exceptions into log, where it can be useful. See https://issues.jboss.org/browse/JBEAP-6041 for more details.

It happened to me twice elytron doesn't log exceptions into log, which would be useful for me, but instead just ignore it. I get to them, once I was debugging code.

Please review also other exception handling places, if exceptions are handled correctly.
