The default for an Alarm reminder is 0 minutes before event (the moment the event starts), but once you change it to something else, you cannot change it back 0 minutes before... the choice does not let you choose 0 ... 1 is the lowest selection you can make.

Reproducible: Always

Steps to Reproduce:
1.Create a new event, and select REMINDER and choose "5 minutes before"
2.Now select REMINDER again and choose "Custom"
3.You can choose 1 minutes/hours/days before event starts, but you cannot change the 1 to 0 ...  "The moment the event starts/ends" is not an option anymore.


Expected Results:  
Should be able to choose 0 minutes/hours/days before event starts, or have a third Radio Button under Custom -> Reminder Details that says "The moment the event starts/ends"
