mParticle-Apple-SDK 8.31.0 crash with nil `userActivity.webpageURL`

[nbeadman]

We were forced to do a hot fix last Friday due to a crash in the mParticle SDK that was fixed in 8.31.0 in fix: MPAppNotificationHandler webpageURL issue PR #353.

Now the SDK crashes in 

<compiler-generated> - Line 
@objc MPLaunchInfo.init(URL:options:) + 1912

when called from

MPBackendController.m - Line 383 
-[MPBackendController_PRIVATE processDidFinishLaunching:] + 383

which has the same underlying issue, in that MPLaunchInfo was rewritten in Swift in refactor: Port MPLaunchInfo to Swift by BrandonStalnaker · Pull Request #329 · mParticle/mparticle-apple-sdk and URL cannot be nil.

However, there is nothing in the MPBackendController.m that checks that userActivity.webpageURL is not nil.

I have also submitted this issue to the support portal as ticket: 21240

Any information on how we can work around this issue or even reliably reproduce it would be useful as we are currently relying on Firebase Crashlytics.

Hi @nbeadman, this issue was resolved in SDK v8.31.1 (see #356). Closing this out since it has been fixed, but left open.
