Fix duplicate files / case-sensitivity issues

[kevgathuku]

On a case-insensitive filesystem e.g. on MacOS, I'm having some issues with files that have the same name but the name is in different cases and different content.
e.g. in the attached image, you can see that we have 2 files named accountservice.js and AccountService.js
Same for FolderService.js and MessageService.js

My filesystem is treating those 2 as the same file and git is having issues differentiating the files.

The PR addresses this issue by removing the old files i.e.

• accountservice.js
• folderservice.js
• messageservice.js

This is a blocker for me. Due to the git confusion I can't do much in git right now
e.g. switching branches

Whoops, sorry.

Thanks for fixing this!

Fun fact: a few days ago I even thought to myself: "how do case-insensitive OSes handle these files?" 🙈
