Fixed bug #1355: CCL-queries messed up by binary chars.

Apparently the yaz_iconv_open was passed an empty string - returned
from absent queryencoding setting. We now check for empty string..
I don't like empty string and NULL value to be messed. Function
session_setting_oneval should return NULL for absent value. Empty
string for empty string.
