test: Don't have dangling symlinks in tests (for msys)

There are 2 reasons for this:
  * Under windows, ln() must determine whether the target is a directory or a
    file before creating the link.
  * msys doesn't handle dangling NTFS symlinks well (for example 'ls' will abort
    at that point, claiming the file doesn't exist).

So I have reordered commands to make sure our symlinks don't dangle from the
time of their creation.
