Bug#25376: Incomplete setup of ORDER BY clause results in a wrong result.

Browse Source 
Functions over sum functions wasn't set up correctly for the ORDER BY clause
which leads to a wrong order of the result set.

The split_sum_func() function is called now for each ORDER BY item that
contains a sum function to set it up correctly.
