Some EXDATE are not excluded as expected

• PHP date.timezone: UTC
• ICS Parser Version: 2.1.15 (dev-master)
• Linux

Description of the Issue:

EXDATES are not excluded correctly from g-suite calendar iCal feed.

Steps to Reproduce:

Using the following initialisation for ICal

$ical = new ICal\ICal('https://calendar.google.com/...../basic.ics', [
        'defaultSpan'                 => 2,     // Default value
        'defaultTimeZone'             => 'UTC',
        'defaultWeekStart'            => 'MO',  // Default value
        'disableCharacterReplacement' => false, // Default value
        'filterDaysAfter'             => null,  // Default value
        'filterDaysBefore'            => null,  // Default value
        'skipRecurrence'              => false, // Default value
        'useTimeZoneWithRRules'       => false, // Default value
    ]);

The EXDATES from the following ICAL segment are not removed as expected.

In particular the final date Europe/London:20190911T095000 is not excluded.

However Europe/London:20190925T095000 does appear to be excluded correctly.

I'm experiencing the same behavior. For me it's removing all but the last exdate. It looks like if DTSTART is the same day as the first EXDATE, it does not remove it.
