Subject: [PATCH] Fix crash decoding statuses sent from certain applications

If an application provides its URL as an empty string, decoding it would
cause throw an error because Foundation's URL class does not accept
empty strings. Instead, during parsing, consume the invalid URL and
replace it with a `nil` app URL.
