[Bug] Sidebar can duplicate the same folder twice

Describe the bug

A folder can appear duplicated on the sidebar. Problem persists upon restart.

To Reproduce

Create a "Shared" folder in the "DATA" directory. It should appear in the sidebar. (I've also had instances where these folders don't appear in the sidebar, but I named mine "transfer" if that is more reproducible).
Go to the shell and delete the folder there with "rm"
Go back to Files and click the folder. It should give a "no files found error".
Create a folder in the same location.
Now you have two of the same folder in the sidebar, both of which light up when you click it.

Expected behavior

Either a) the folder in the sidebar never disappearing, but just reconnects to the new folder when created or b) the folder in the sidebar disappears when it is deleted. Would also be nice to be able to add or remove folders from the sidebar, and then have new folders in the sidebar only appear when added, instead of tracking the contents of "DATA".
