Multi entity managers

[ghost]

If you use the DatabaseConfigBundle with multiple entity managers, you get this error:

[Symfony\Component\Debug\Exception\ContextErrorException]
Notice: Undefined index: entity_managers in ...\vendor\unifik\database-confi
g-bundle\Unifik\DatabaseConfigBundle\DependencyInjection\Compiler\Container
Builder.php line 76

Just change
$defaultConnection = $mergedConfig['entity_managers'][$defaultEntityManager]['connection'];

to

$defaultConnection = $mergedConfig['orm']['entity_managers'][$defaultEntityManager]['connection'];

Thanks for merging!
