Title: Correct order of commits in "reorder" solution

The solution incorrectly expects "Third commit" to be the root commit,
"Second commit" to be the second commit, and so on.

These changes correct the order. The solution now expects that "Initial
Setup" is the root commit, that "First commit" is the second commit, and
so on.
