twitter: fix misparsing of https://twitter.com/i/status/:id urls.

Fix URLs like `https://twitter.com/i/status/943446161586733056` parsing
the username as `i`. This led to the new artist page recommending the
tag name `i` when creating an artist for a source like this.

Also fix these URLs not being normalized to `https://twitter.com/:username/status/:id` after upload.
