Adding a slash to branch name when using "git checkout -b" goes into "detached head" mode

Steps to reproduce:
- Type in "git checkout -b feature/branch" on the default tool state
- You are now on "detached head" mode

I noticed that the coloring of the branch matches what's used for remotes, so maybe it's related to that. Just guessing.

BTW this tool is simply amazing, kudos on making it!
