Why is nil session handled only partly in retryable/write_worker which was added from 2.19.0?

I came across an issue while using version 2.19.2 and 2.19.3 with mongodb 3.6 in a setup with a primary and 2 replicas.
In write_worker.rb line 107 there is this bit of code session&.client.options[:retry_writes] which seems to have been thought to handle a nil session but not implemented completely as when the session is nil the client will be nil and will crash on accessing options. If I downgrade to 2.18.3 it's working fine as this bit of code isn't there.

Hi @raulalexe , thank you for reporting this! I created JIRA ticker for the problem - https://jira.mongodb.org/browse/RUBY-3358 - to have the team review this and identify next steps.

Hi @comandeo, this issue is preventing us from upgrading. Is there an ETA on a fix for this?
