Crash on Activate when being asked to allow notifications

[TomasHubelbauer]

Hi, I just got RSToDoList off the AppStore based on this GitHub repository. It looks great, but when I am asked to allow notifications during onboarding, when I click Activate, the app consistently crashes. But - the notifications do get enabled in the Settings it seems. I had do dismiss the prompt for notifications using the Not Now button for it to go away though, even though now in the Settings I see them enabled. The notifications work - I set a reminder and got a notification. Let me know how I can help debug the issue.

I fixed this by just running that handler on the main thread no matter what.
