Subject: [PATCH] uci: Fix uci_delete() when ptr->value is empty string
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

After fix for deleting list elements by index this function was
broken and didn't allow to invoke from command line:
uci set some.fancy.list=''
i.e. list wasn't cleared
