Prepend Child Bundle paths before the parent
bug #9112 Prepend Child Bundle paths before the parent (trsteel88)

This PR was submitted for the 2.3-dev branch but it was merged into the 2.3 branch instead (closes #9112).

Prepend Child Bundle paths before the parent

This fixes #9085

Say you have AcmeDemoBundle and AppDemoBundle. AcmeDemoBundle is the parent of AppDemoBundle.

If you load templates using @AcmeDemoBundle/ControllerDir/template.html.twig it means that you cannot override the template in AppDemoBundle. The patch below prepends the AppDemoBundle Resources directory to the AcmeDemo namespace.

The namespace directories would not result in:

```
[AcmeDemo] => Array(
    [0] => [absolute-dir-here]/src/App/DemoBundle/Resources/views
    [1] => [absolute-dir-here]/app/Resources/AcmeDemoBundle/views
    [2] => [absolute-dir-here]/src/Acme/DemoBundle/Resources/views
)
```

The `DoctrineParserCache` returns `false` when there is no entry (https://github.com/doctrine/cache/blob/master/lib/Doctrine/Common/Cache/Cache.php#L52).
But the `ExpressionLanguage` class expects `null` to be returned by the `ParserCacheInterface`, which causes the expressions to not be parsed when using a `DoctrineParserCache`.
