Project fileModified events can be emitted before file: protocol supporter is registered

[misode]

During project#ready, the listDependencyFiles and listProjectFiles tasks are started in parallel. However a problem occurs when listProjectFiles finished before listDependencyFiles, and the watcher notices a file has been modified. Since this.#watcherReady has been set to true it will emit a fileModified event, which will try to read the file. This in turn will try to find the file: uri protocol, but that is only registered at the end of listDependencyFiles, and it is possible that hasn't finished yet.
