Description

When I create a branch from a "detached HEAD" state (such as from a commit), the branch is created with a different history (my assumption is that it's master or the default branch)

Version

• GitHub Desktop: 1.5.0

• Operating system: macOS 10.13.6

Steps to Reproduce

1. Check out a commit in terminal (I did git checkout a813cc1 as an example) and switch to Desktop
   
2. In Desktop, create a new branch. Desktop should warn you that the new branch will be based off of the currently checked out commit.
   
3. After creating a new branch, look at the history.

Expected Behavior

I'd expect the latest commit to be the one that I checked out (I did git reset --hard a813cc1 to simulate this in the UI):

Actual Behavior

The latest commit in the branch is more recent than the one I originally checked out:
