As part of the performance improvements for listing sessions for v0.9.0,
the view used to retrieve sessions for listing was updated to no longer
include a join on session_connection. However, a later migration that
was adding additional columns to this view inadvertently re-added the
join and session_connection columns. This resulted in requests to list
sessions performing this join, and returning additional rows for each
connection in a session. The application would ignore this additional
data, since it is no longer returned via the API. This would be
particularly impactful in cases where there are a large number of
connections per session, as this would greatly increase the amount of
data returned by the database.
This fix removes the session_connection join from this view, which
should restore the original performance improvements even in cases where
there is a large number of session connections per session.
