Graph: Support EXDATE on initial ICS upload event Creation

[tmcqueen-materials]

I found another edge case -- when creating a new event via CalDav with an ICS file that has one or more EXDATE's, the event is created without the EXDATEs. It appears that the new event create path creates the json version of the event, but then does not add (or otherwise handle after creation) the modified occurrences. Should be easy to reproduce with any ICS file with an EXDATE that creates a new event.

Thanks!

Any chance you could upload an anonymized .ics file here for testing purposes, @tmcqueen-materials ?

@esabol : Sure, here you go.

That's correct, assumption was that you need to create an event before adding exceptions.

Didn't take into account the import use case.
