App version

• Tested with 4.0.x

Installation source

• homebrew

Describe the bug

• Events with attendees that have an invalid (nil) email address cause Meetingbar to crash

To Reproduce

1. Create a meeting with one or more attendees.

2. At least one attendee should have a nil email address. In my case, it is a Microsoft Exchange calendar that has multiple attendees with x500 email addresses. e.g. /o=ExchangeLabs/ou=Exchange Administrative Group (FYDIBOHF23SPXXX)/cn=Recipients/cn=5e17910fea164345b55313d0f6f4fXXX-John Smit. This email address shows as nil

3. Launch Meetingbar (immediate exit)

4. Launch Meetingbar via cli, returns:
