Describe the bug

After update from 4.7.6 to 4.7.7 collection days no longer show on the calendar. The sensors appear to still be working correctly.

Appears to be caused by 50c62a0958026a2658893f413846982f97d8c8b1

Calendar.py still references the old function https://github.com/bruxy70/Garbage-Collection/blob/master/custom_components/garbage_collection/calendar.py#L104
