rebase: rebasing can also be done when HEAD is detached

Browse Source 
Attempting to rebase when the HEAD is detached and is already
up to date with upstream (so there's nothing to do), the
following message is shown

        Current branch HEAD is up to date.

which is clearly wrong as HEAD is not a branch.

Handle the special case of HEAD correctly to give a more precise
error message.
