tests: fix Git on Windows sometimes failing on ' or ` in file:/// URLs

Some Git versions will fail when cloning a repository like:

  git clone file:///path/to/strange-file-'`foobar myclone

Since '` (and some other characters) are filtered anyway (in
lib.utils.repo_name_slug) I think this test doesn't need to test those
characters.
