Running tests locally creates a lot of folders and files in user home directory and does not do cleanup

[shashfrankenstien]

There are a lot of cases where Path.home() is used as destination location when running tests against local sftp server. There is no cleanup of these files and folders. Would you consider using a subfolder instead of home directory so cleanup can be applied through pytest fixtures at the end of the test session?

Example test:

def test_put_d(lsftp):
    '''test put_d'''
    localpath = Path(mkdtemp()).as_posix()
    remote = Path.home()
    build_dir_struct(localpath)
    local = Path(localpath).joinpath('pub')
    lsftp.put_d(local.as_posix(), remote.as_posix())

    rmdir(localpath)

pub folder is not cleaned up

Addressed the tests that I could find that produce these artifacts and have switched them to a tmp directory. The changes have been pushed to your PR about the missing/invalid private key path.
