patchcommit: check for empty message before the check for untouched template

> The check for whether the template given to 'git commit' is untouched
> is done before the empty message check. This results in a wrong error
> message being displayed in the following case. When the user removes
> everything in template completely to abort the commit he is shown the
> "template untouched" error which is wrong. He should be shown the
> "empty message" error.
>
> Do the empty message check before checking for an untouched template
> thus fixing this issue.
