Subject: [PATCH] Use `replaceWith` to transition from missing crate

When visiting a crate that doesn't exist the application uses
`transitionTo` to change the route to the index route. This allows the
user to navigate back to the same missing crate route which breaks the
browsers back button.

* Replace `transitionTo` with `replaceWith` to avoid adding history
  entry.
