f27791b7 - Raise the last known account data / state event for an update

Raise the last known account data / state event for an update This is to better support the react-sdk in trying to identify what actually changed in settings instead of re-firing everything. Overall this change differs from `prev_content` semantics as it's the last known *stored* event, not whatever the server thinks may or may not have changed.
