[DX] Potential missing annotation route import

Register controller route when a bundle is generated in xml, yml and php, but we want to generate a crud with annotation
Also, we would need to make sure that if we *do* find an annotations import, that it's not for a different file. For example, suppose our new controller is called `BlogPostController`:

`resource: @FooBundle/Controller` => our new controller annotations will be imported just fine
`resource: @FooBundle/Controller/OtherController.php` => our new BlogPostController annotations will *not* be loaded, so this should return `false`
