The entity manager is not available

Bug Report

Q	A
BC Break	yes/no
Version	3.0-dev

Summary

Symfony 5.0.4
Doctrine Migrations: 3.0-dev
Doctrine Migrations Bundle:3.0-dev

During running the diff command I get the error: The entity manager is not available. even though I configured the em setting and the entity manager exists.

Current behavior

I've configured the entity manager setting, but when building the container the bundle's extension does not get access to the entire container. As such it cannot find the entity manager service that is configured or the default one. It then defaults to using the Doctrine default connection. The problem shows up in doctrine/migrations/lib/Doctrine/Migrations/DependencyFactory.php:224 when trying to create the OrmSchemaProvider. Since the DependencyFactory was built using fromConnection() the entity manager is null.

How to reproduce

1. configuration:
   // config/doctrine_migrations.yaml

doctrine_migrations:
  em: default // or any other entity manager

2. clear cache to rebuild the container
3. run bin/console doctrine:migrations:diff

Expected behavior

The command would execute using the configured entity manager.
