Use a Galaxy root path with a space for converters and mulled tests

Also:
- Fix integration tests for checkout@v2 action: the working directory is not
  updated any more when `path` is specified
- Use checkout action to clone the galaxy-test-data repo and rsync to move
  them in place
- Install virtualenv<20 when running tests via tox in a directory containing
  spaces, xref. pypa/virtualenv#1660
