combine-diff: move show_log_first logic/action out of paths scanning
Judging from sample outputs and tests nothing changes in diff -c output,
and this change will help later patches, when we'll be refactoring paths
scanning into its own function with several variants - the
show_log_first logic / code will stay common to all of them.
NOTE: only now we have to take care to explicitly not show anything if
parents array is empty, as in fact there are some clients in Git code,
which calls diff_tree_combined() in such a way.
