Giom Foret 422ad1c514 App extension - Improvement: Reduce memory consumption.
Force the ShareExtensionManager to release the primary view controller when the action is completed.

We observed that `dealloc` is called for this view controller when the request is cancelled with error (`cancelRequestWithError`), but it is not called when the request is completed (`completeRequestReturningItems`).
