Fix tests if there are hooks generated by templates

[lufia]

If there are custom hooks in ~/.git_template/hooks, they can occur an error on such as pre-commit hooks.

I have a pre-commit hook in the template dir:

function must()
{
	local v=$(git config --get $1)
	if ! [[ $v = $2 ]]
	then
		echo >&2 "$1=$v: must match $2"
		exit 1
	fi
}

must user.name xxx
must user.email xxx@example.com
