'secret' plots sometimes show up as 'private' on cloud

[Kully]

for _ in range(50):
    fig = dict(data=[{}], layout={})
    plot_url = py.plot(fig, filename='test_folder/title', fileopt='new', auto_open=False, sharing='secret')

^^^Running this code above makes a folder and puts secret graphs into that folder. Out of 50 plots I made, 4 of them were set to private in the cloud.
