Rendering avatars throws a RuntimeError

[martinspain]

Describe the bug

When rendering comments on an entry, if a commenter has a user photo set, a RuntimeError will be thrown:

Twig Runtime Error – [Twig\Error\RuntimeError]
Calling unknown method: craft\models\Volume::fileExists()

This is caused by the {% set avatar = craft.comments.getAvatar() %} line in templates/_special/_includes/form.html, which calls CommentsHelper::getAvatar(). A private _assetExists() method then tries to check if the asset exists:

$asset->getVolume()->fileExists($asset->getPath());

It's calling the fileExists() method on the asset's Volume model instead of the FsInterface of the Volume, which is what's causing the error. I believe the line should be:

$asset->getVolume()->getFs()->fileExists($asset->getPath());

Steps to reproduce

1. Render a set of comments against an entry where at least one of the commenters has a user photo set on their User account.
2. Observe the error.
