Reviewed by Per Arne Vollan.
The block passed to `[WKMarketplaceKit requestAppInstallationWithTopOrigin:]`
may get called on a non-main thread, causing us to call addConsoleError()
on that thread and crash since we expect `addConsoleError()` to always
run on the main thread.
Address the issue by calling `ensureOnMainRunLoop()` to get back to the
main thread before calling `addConsoleError()`.
