Describe the bug

In 4.5.2 and below components with v-if would have 100% test coverage, now with 4.6.0 and above they will report the first line of the Vue component (<template>) as not being covered in tests.

I've made the min-repro as simple as possible, it boils down to this:

Example:

<template>
  <div v-if="true"></div>
</template>

<script>
export default {
  name: 'App'
};
</script>

import { shallowMount } from '@vue/test-utils';

import App from '../../src/App.vue';

describe('App.vue', () => {
  test('Shallow mount', async () => {
    const wrapper = shallowMount(App);

    expect(true)
      .toEqual(true);
  });
});
