test: use really invalid hostname
test: use really invalid hostname

On my slow Ubuntu 14.04 machine, this fails to resolve the host name
used (`no.way.you.will.resolve.this`) and it times out in local testing.
This patch uses an invalid name (`...`) and does stricter validation of
the error returned.
