pgAdmin 4 commit: Fix for Exception when the server is restarted. Fixes

Fix for Exception when the server is restarted. Fixes #2713

This issue was caused because we recently added session_write_delay in session.
So session won't be written/updated to disk from memory until specified seconds are elapsed.

However we must forcefully write/update session to disk if user loges in or out irrespective of session_write_delay to keep sessions from memory and disk in sync as user logged in status is kept in session.
