Fix --list prints empty cell as "(null)"

To illustrate the issue before and after this fix: # /usr/bin/yad --list --print-all --column=A a '' c a| (null)| c| # ./src/yad --list --print-all --column=A a '' c a| | c| The empty string '' in the second row results in a NULL C pointer, which g_printf prints as "(null)". The fix consists of passing the empty string "" to g_printf when the pointer is NULL.

Fix --list prints empty cell as "(null)"
