[DoctrineBundle] Doctrine 2.2 compatibilty

Bug fix: yes
Feature addition: no
Backwards compatibility break: no
Symfony2 tests pass: yes

Doctrine 2.2 does not initialize reflection anymore when in a code-generation context. This fails with the Symfony Metadata Factory that acceses the ReflectionClass after checking that the entity class_exists. This occurs when using code-generation in combination with the annotation driver.

This PR fixes the problem.
