[FIX] google_calendar : fix default reminder

To reproduce
============

- Sync Google Calendar to Odoo
- Create an event in GCaledar without setting a notification
In Odoo Notification reminder is set

Purpose
=======

we use default reminder given by Google which is notification 30 minutes before even if the event
doesn't have a reminder.

Specification
=============

To solve the issue we use empty reminder instead of the default given by google if no reminder is set.
