deephaven_server.Server fails when handling bindTable gRPC calls

[jnumainville]

Description

Calling bind_table on pydeephaven session fails.

Steps to reproduce

1. Start deephaven via python, either with

   $ deephaven server
   

   or by running python

   $ python
   > from deephaven_server import Server
   > Server().start()
   

   etc.

2. From some gRPC client, attempt to bind a table to a scoped name

   from pydeephaven import Session
   
   session = Session(
       auth_type="io.deephaven.authentication.psk.PskAuthenticationHandler",
       auth_token="token",
   )
   
   table = session.time_table(period=1000000000).update(formulas=["Col1 = i % 2"])
   session.bind_table(name="my_table", table=table)
   

   Can also achieve this effect by using the web IDE's "upload CSV" functionality. Bidirectional plugins are also likely to trigger this, by sending an object from the client to the server.

Expected results

The table is bound without error

Actual results
The following errors (the first in the jupyter console, the second on the server)
