Codespace creation from branch on template repo defaults to a codespace "created from the template"

Body

When inside a template repository, if you are trying to create a codespace from a branch (New with options... -> Select Branch) it will make a call to github.com/codespaces with the form value codespaces[template_repository_id] set.

This creates a codespace "From a template" that has no connection back to the repo it was created from. This makes it impossible to create repos on branches through the ui, when developing the template repository.

If you make the same call to github.com/codespaces without the template_repository_id set, then it works fine.

I would expect the above image to create a codespace on a branch in a template repository, but instead i get this:

The second one in this picture was created by omitting the template_repository_id form value, and it successfully opened a codespace on the branch.
