Bug: The blog post feed component does not work on nested pages due to not using routes

[caendesilva]

Steps to reproduce:

1. Run the following commands:

php hyde publish:homepage posts -n
mkdir _pages/posts
mv _pages/index.blade.php _pages/posts/index.blade.php
touch _posts/foo.md
php hyde build

2. Visit _site/posts/index.html
3. Click on the link for the post
4. It leads to _site/posts/posts/foo.html instead of _site/posts/foo.html

Expected behavior:

Clicking on the link for the post should lead to _site/posts/foo.html.

Actual behavior:

Clicking on the link for the post leads to _site/posts/posts/foo.html.

Cause of the issue:

The issue is caused by article-excerpt.blade.php where the link uses the legacy style of links: href="posts/{{ Hyde::formatLink($post->identifier . '.html') }}" instead of $post->getRoute, which dynamically resolves relative paths.

Possible solution:

Use $post->getRoute instead of Hyde::formatLink in article-excerpt.blade.php.
