commit: 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.
