Title: Use Same Shared Event Manager across the board

Make sure that at all points where the SharedEventManager is
being initialised, it is using the same method.

This change makes it so that when calling
```php
$serviceManager->get('SharedEventManager');
```

It will initialise in the same manner as if we were to call

```php
$eventManager->getSharedManager();
```

Without having first set the Shared Manager in the Event Manager

This also affected the ActionControllerTest - as it was expecting the
SharedEventManager to be reset between requests.
