Make unpack-tree update removed files before any updated files

This is immaterial on sane filesystems, but if you have a broken (aka
case-insensitive) filesystem, and the objective is to remove the file
'abc' and replace it with the file 'Abc', then we must make sure to do
the removal first.

Otherwise, you'd first update the file 'Abc' - which would just
overwrite the file 'abc' due to the broken case-insensitive filesystem -
and then remove file 'abc' - which would now brokenly remove the just
updated file 'Abc' on that broken filesystem.

By doing removals first, this won't happen.
