Merge lp:~artmello/ubuntu-calendar-app/ubuntu-calendar-app-fix_set_date_new_event into lp:ubuntu-calendar-app

[Arthur Mello]

Make sure that startDate/endDate is defined before setting date time

Currently we can see this when creating a new event from "New Event" bottom edge: file:///opt/click.ubuntu.com/com.ubuntu.calendar/0.5.800/NewEvent.qml:329: Error: Cannot assign [undefined] to QDateTime

This MR checks if property is undefined before setting it.

Tests necessary:
----------------
1. Make sure that events with same start/end time imported from google will be displayed with correct colors if they are past or future ones;
2. Make sure that events with different start/end time imported from google will be displayed with correct colors if they are past or future ones;
3. Make sure that when editing an existing event the correct start/end time are displayed
4. Make sure that when creating a new event it has the correct start/end time
5. Guarantee that no error is displayed while executing the above
