Propagate query scope changes even if script throws a RuntimeError

[nbauernfeind]

The failing example looks like:

from deephaven import TableTools
x = TableTools.emptyTable(10)
y = x.update("I = jj")

Followed by the corrected version of the script:

from deephaven import TableTools
x = TableTools.emptyTable(10)
y = x.update("I = ii")

Which caused an NPE since the listener is receiving the message that x is being updated, but it was never told about it in the first place. Note that the listener expects that an update is actually an update to a field it knows about. The python session can't tell where x came from during the second call.

We should try to capture this eventually as an integration test of sorts.
