Create new empty project and make an initial commit. 2. Create a new branch and make a commit. 3. Change the default branch of the project to the new branch. 4. Go to The Repository->Branches page. 5. Hover over the divergence graph of the master branch, it will read "1 commits behind master, 0 commits ahead" ### Example Project https://gitlab.com/0neblock/test-branch-divergence-project ### What is the current *bug* behavior? The divergent message shows the master branch, even it it is not the default branch. ### What is the expected *correct* behavior? The message should show the default branch. ### Relevant logs and/or screenshots  ### Possible fixes https://gitlab.com/gitlab-org/gitlab-ce/blob/master/app/assets/javascripts/branches/divergence_graph.js This file has 'master' hardcoded for the DivergenceGraph Vue component, it should instead pass the name of the default branch.
