[Repository] Impossible to use a repository that implements ServiceEntityRepositoryInterface

[Maxime Veber]

Sylius version affected: all

Description
It is possible to use a repository that inherits from ServiceEntityRepository but not a repository that "just" implements ServiceEntityRepositoryInterface. Besides it's useful when you already extends from some other base repository.

Steps to reproduce

1. Create a repository that implements ServiceEntityRepositoryInterface
2. Use it in the resource bundle config

Possible Solution

Check against the interface instead of the class.
