[BUG] missing user/pass for register() results in KeyError: 'org_name' in plot()

[DataBoyTX]

Describe the bug
missing user/pass is not failing on register(), but results in KeyError: 'org_name' on plot() call

To Reproduce

import pandas as pd

graphistry.register(api=3,  
                    protocol  = "http",
                    server    = "nginx",
                    username  = os.getenv("NON_EXISTENT_ENVAR"),
                    password  = os.getenv("NON_EXISTENT_ENVAR")
                   )

edf = pd.read_csv('https://raw.githubusercontent.com/graphistry/pygraphistry/master/demos/data/honeypot.csv')

graphistry.edges(edf, 'attackerIP', 'victimIP').plot()

Expected behavior
expect register to fail or warn

Actual behavior
