When repositories are synched, the backend needs to update the local references to the ones set on the remote repository. The backend processed all the references, including those up to date. This made the synchronization very slow.
With this commit, only the references that were updated on the remote repository will be modified locally. We have improved the performance by 2. Repositories are in sync two or more times than before.
