Carlos Martín Nieto c099655fc0 TreeEntry: compare ids when two entrie sort equally
The function we were using `git_tree_entry_cmp()` is only meant for
git-compatible sorting in a tree and thus does not take the id into
account. This is however important in order to keep value equality. In
order to avoid issues with assymetry, we compare the id any time when
two entries are equal according to their position in a tree.
