fix silent Oracle connection failures

::Storage::DBI::_server_info was eating connection exceptions by
ignoring exceptions from $dbh->get_info, but this information is
important for _rebless when e.g. determining which class to use based on
the DB server version, so rethrow the exceptions when
$self->{_in_determine_driver} is true.
