Error when preloading is enabled

[Gwemox]

API Platform version(s) affected: 3.1.6 - 3.1.7

Description
After upgrading to v3.1.7 api-platform crashes on production where opcache.prelaod is enabled. On v3.1.5 worked fine.
Warning: Cannot declare interface ApiPlatform\Api\FilterInterface, because the name is already in use

Error similar to api-platform/api-platform#2284

How to reproduce

• Upgrade to v3.1.7
• Make sure opcache.preload is enabled. (I use the Symfony's default preload script);
  • opcache.preload_user=www-data
  • opcache.preload=/var/www/config/preload.php
• Open /api or any api-platform endpoint

Possible Solution
Check if interface exist before declaration.

src/Metadata/FilterInterface.php

class_alias(FilterInterface::class, \ApiPlatform\Api\FilterInterface::class);

to

if (!interface_exists(\ApiPlatform\Api\FilterInterface::class)) {
    class_alias(FilterInterface::class, \ApiPlatform\Api\FilterInterface::class);
}
