Calendar event display not displaying changes properly

[mauricioduarte01]

Hi, all of the information below was provided thanks to Mr.wayne (out there).
FP2, Hammerhead, 16.04 rc/dev.

Steps to reproduce:
If you press 'sync' button, it seems like nothing is happening on UT. For example, if you create a test event on NC and press 'sync' on device, nothing appears to happen. Same thing the other direction.

*What happens:"
Then i realized the problem is not the sync, but the display 'refresh' (not sure what to call it). If i change the view from week to day to week again, the events appear or disappear correctly, or if i shut down calendar app and reboot it. So it appears the sync is working well but the display in UT calendar is not refreshing properly.

*Expected behavior:"
Calendar should refresh when pressing the refresh icon and display the changes in the different view modes, also it would be good to have a notification message after pressing the refresh button letting us know that the syncing was completed successfully -or not-.

Thanks.
