Set only global timestamp for non-exempt avalanche notifications
During notification avalanche events, update the last notification posted timestamp
for non-exmept notifications as the global timestamp only: this avoids attentuating
exempt (eg. conversation) notifications that are posted after regular notifications
during the avalanche events.
