Toggle button to isolate branch and run test suite on changes (solo a vbranch)

[gitbutler-client]

It would be really neat to have an "isolate branch" toggle button which would unapply all the other branches for you by visually greying them out, and when pressed a second time, would bring them all back.

This would allow running your test suite on just the changes in one particular branch to ensure that you've not got any failures that are potentially fixed as a side-affect of another branch in your workspace (or vise versa!)
