Opening an app via a fileId-only URL throws an uncaught cancel error #4122

Bug Description

Opening an app through a fileId-only URL throws an uncaught cancel error. In AppWrapper.vue the route gets the drive alias added inside the restartable loadResourceTask, the file-context watcher then restarts the task and the first await loadResourceTask.perform() rejects with vue-concurrency's cancel, which nobody catches.

Reproduction Steps

1. Open /text-editor?fileId=<id of a .md file>

Expected Outcome

The editor opens without an uncaught error.

Actual Outcome

An uncaught cancel error while the URL gets the drive alias added, then the editor loads.
