template option is not respected

[jsamr]

template:'simpleAtForm' option is not taken into account. fullPageAtForm is used instead.

<template name="simpleAtForm">
    <div class="simple-at-form">
    {{> atForm}}
    </div>
</template>

AccountsTemplates.configure({
  enablePasswordChange: true,
  sendVerificationEmail: true,
  showResendVerificationEmailLink: false,
  overrideLoginErrors: false,
  continuousValidation: true,
  showValidating: true,
  negativeFeedback: true,
  showReCaptcha: true,
  defaultLayout: 'layoutTemplate'
});
AccountsTemplates.configureRoute('signUp', {
  template: 'simpleAtForm',
  name: 'signup',
  path: '/user/register',
  title: "S'enregistrer",
  redirect: '/user/login'
});
