Downloads don't progress past enqueued.

I'm trying to download files from my webserver, there is required authorization, so I'm sending an authorization header, like so
```
task.taskId = await FlutterDownloader.enqueue(
url: task.link!,
headers: {'authorization': '[Bearer ${store.state.auth.accessToken}]'},
savedDir: _localPath,
saveInPublicStorage: true,
);
```

I have my background isolate running and getting updates, but it just gets the queued update, and nothing else, despite however long I wait.

To reproduce the bug, Just try to download a file and have your background isolate watching. I imagine this might have something to do with authorization, but if that is the case, I would expect some kind of error reporting so I'm not just shooting in the dark like I currently am.

**Expected behavior**

I expect the download to start from the queue instead of just sitting there with the queued status indefinitely.
