fix: Added enterprise checks for case where object name is a string #36

Fixes #35

Added checks for enterprise info in case where object name is a string

Ran the following code and verified the chart appeared:

from deephaven_ipywidgets import DeephavenWidget

connection_info = "connection"
session_mgr: SessionManager = SessionManager(connection_info)
session_mgr.password("username","password")
session = session_mgr.connect_to_new_worker(name=None, heap_size_gb=1.0)

session.run_script("""
from deephaven import empty_table
from deephaven.plot.figure import Figure
t = empty_table(100).update(["X=i", "Y=i*i"])
f = Figure().plot_xy(series_name="X vs Y", t=t, x="X", y="Y").show()
""")

display(DeephavenWidget("f", session=session))
