stats_tree: fix the comparison routine for COL_AVERAGE

Generally, the average is calculated as node->total / node->count.

The curent code does not handle the case where we compare two nodes
and both have count == 0. It defines one of the nodes to be bigger.
This triggers (at least on Windows) an assertion about invalid operator<.

To fix this, we define average = 0 for a node with count == 0.
We can then simply compare the two averages.
