Files from double nested folders being downloaded twice

[Beebeeoii]

Describe the bug
This bug is quite random and I am not sure what is happening as it appears to affect 2 of my modules. Files in doubly nested folders are being downloaded twice - once in the correct location (which is to be in the double nested folders), and another time in the main directory.

For eg, we have a file 1.txt in ../CS2040S/Lectures/Lecture 1/1.txt, 1.txt seems to be downloaded in both ../CS2040S/Lectures/Lecture 1 (which is the correct behaviour) and ../CS2040S/Lecture 1 (which is the wrong behaviour).

To Reproduce
Simply syncing. However, it should be noted that I did not encounter this issue previously. It only surfaced recently without any changes to Lominus and the folder structure for the module is exactly the same.

Issue should be fixed by c069d18. Files are duplicated because retrieval of folders in a module returns ALL nested folders. this resulted in duplication of files as each folder is being processed and files in each of them are being downloaded multiple times.
