### Summary The error message when creating a new MR in an existent branch through the UI is not very helpful  How do I switch to a branch from this view? ### Steps to reproduce 1. Edit a file 1. Change the target branch to a new one 1. Click commit changes 1. Don't create a new MR 1. Go back to the edit page 1. Edit some more 1. Try to commit to the same branch ### What is the current *bug* behavior? Although the message is correct it is not very helpful for the end user since in that page there is no way to go that branch ### What is the expected *correct* behavior? 1. Give the user a link to that branch with the edited file changes.
