The asynchronous nature of extension loading, session loading, and more, makes the code racy as to what is initialized first, and hard to debug. Additionally, since gjs is single-threaded, the only code we're running in a thread anyway is readdir, which is going to be I/O bound, so the code here is actually likely to be faster. Drop this in favor of some good old fashioned synchronous loading.
