Refactor source strategies to remove the `canonical_url` method. `canonical_url` returned the URL that should be used as the source of the post after upload. Now we simply use `Source::URL#page_url` to determine the source after upload. If the source is an image URL that is convertible to a page URL, then the image URL is used as the source. If the source is an image URL that is not convertible to a page URL, then the page URL is used as the source. This simplifies source strategies so that all they have to care about is implementing the `Source::URL#page_url` and `Sources::Strategies#page_url` methods, and the preferred source will be chosen for posts automatically.
