Before this commit when accepting a recurrent event from google calendar with option "this event", it didn't reflect on odoo calendar.
This happened due to the write_date check which applies google update only if their write_date is after odoo write_date,
but multiple updates from google might change some events write_date to now, which causes other google updates to get discarded.
This commit aims to fix this issue by keeping the write_date of the affected events before applying any google updates, and considering these dates instead of the live odoo write_date.
