Event notifications on internet calendars are replicated at each synchronization

Event reminder notifications on internet calendars are replicated at each automatic synchronization

Steps to reproduce:

• configure the link to a Google calendar
• set up automatic synchronization every 15 minutes
• create an event on the Google calendar with reminders
• at the first synchronization the notification is sent (via email or on WebTop)
• at the next synchronization (after 15 minutes)

Expected behaviour:

• notification no longer arrives

Actual behaviour:

• notification arrives either via email or on WebTop after each synchronization.

The notification arrives on the interface every time even if the "Ignore" button was clicked on the previous message
