Crash in com.apple.WebKit.WebContent at com.apple.WebKit:
WebKit::WebExtensionAPIEvent::removeAllListeners

Reviewed by Timothy Hatcher and Brian Weinstein.
This patch is a speculative fix for a crash introduced by 289222@main, as I
have been unable to reproduce the problem.
The crash is almost certainly happening because we're dereferencing a nullptr,
so the fix is to simply add null checks prior to dereferencing.
