Allow git branches graph to set auto with other branches

[Thaina]

Git graph auto is great when we have made new branch and want to track on it. But some repo might have many important branch that should be shown along with the branches related to current

So I wish that Auto option should not be radio checkbox that remove other options. But allow selection of Auto along with other branches. So the ide will suggest auto for the current branch but we can still see the graph of other important branches we need
