Bug: branch checkout is detached if the case doesn't match

If you try to switch to a branch (e.g. `master`), but get the case wrong, e.g:

    git switch MASTER
    git checkout MASTER
    git switch Master
    git checkout Master

etc. then it autocorrects the case (bad idea but ok), but it also enables the `--detach` flag! In other words

    git switch Master

acts like

    git switch -d master

Very unexpected!

Cheers,

Tim
