All-day recurring event does not show the first event

Creating a monthly, annual or personalized recurrence (every 3 months for example) of an "all day" event the grid does not show the first event in the chain.

Steps to reproduce:

• create an all-day recurring event as an the attached screenshot

Expected behaviour:

• the calendar grid shows all recurring events

Actual behaviour:

• the grid does not show the first event in the chain but only from the second onwards

NOTE: This problem was not present in the previous release (5.7.5)

This could be a regression related to this issue: WTCALENDAR-95
