Cargo previously erroneously updated the registry whenever a new dependency was added on a crate which already exists in the DAG. This commit fixes this behavior by ensuring that if the new dependency matches a previously locked version it uses that instead. This commit involved a bit of refactoring around this logic to be a bit more clear how the locking and "falling back to the registry" is happening. Closes rust-lang#2895 Closes rust-lang#2931
