Remove git amend

Accidental git amend on top of the Head

# Move the current head so that it's pointing at the old commit
# Leave the index intact for redoing the commit
git reset --soft HEAD@{1}

# commit the current tree using the commit details of the previous
# HEAD commit. (Note that HEAD@{1} is pointing somewhere different from the
# previous command. It's now pointing at the erroneously amended commit.)
git commit -C HEAD@{1}
