hotfix Workaround for DoctrinePHPCRBundle regression
feature [#479] Upgrading all functional tests to use minimal configuration

- Functional test:
  - applications now live in `/*Bundle/Tests/app`
  - extend SuluTestCase
  - include "SuluTestBundle/Resources/dist/config.php"
      - Which dynamically loads different configurations based on the
        environment variables SULU_PHPCR and SULU_ORM
  - kernels now extend SuluTestKernel which includes all
    the bundles required for a standard Sulu.
- Removed repeated configuration files
