The handle role change project updated the operation of subscriptions such that if a server-initiated bootstrap was started while a subscription was being bootstrapped, the subscription will be reset to the Pending state and the m_flx_last_seen_version will be reset to the m_flx_active_version value.

There was a comment posted on PR #7675, which contained this change, regarding updating the m_flx_last_seen_version when a sync session starts or when a subscription QUERY_ERROR occurs and possibly updating the validation in the SessionWrapper::on_flx_sync_progress() function regarding this value.

Since this change could have potential side effects with progress notifications which relies on the m_flx_active_version value, it was pulled out into a separate task to isolate and investigate these changes.
