[BUG] "Business Shared Folder has been deprecated" message is shown when no business shared folders have been configured

[Slater91]

Describe the bug
When configuring a SharePoint folder, the message that "Business Shared Folder has been deprecated" is shown. The message links to the page on OneDrive for Linux's wiki, which actually does not state that the feature is deprecated at all. Aside from this, the issue is that no business shared folder is configured, as the configuration is about a SharePoint folder. The option "sync_business_shared_folders" is in fact set to false in the configuration file. This seems to be a poor implementation of the check, as it always flares up whether the option is set to true or false.
It should also be noted that the configuration file was the stock one, downloaded from the OneDrive for Linux GitHub and then modified. OneDriveGUI proceeded to remove any and all comments and to add its own stuff (which it really shouldn't do!), including adding the "sync_business_shared_folders = false" option, so this is an entirely self-inflicted issue.

To Reproduce
Steps to reproduce the behavior:

1. Setup a SharePoint folder using the method explained in the wiki
2. Import the configuration in OneDriveGUI (as, due to issue 271, setting up SharePoint entirely inside OneDriveGUI does not work)

Expected behavior
If the option is set to false, it is ignored and no warning message is shown.

Log
If applicable, add relevant output from log file /tmp/onedrive-gui/onedrive-gui.log.

Just to add a bit more information, I can confirm that OneDriveGUI indeed does break itself. I removed the option sync_business_shared_folders = false last Friday, before I opened this bug report, and today it's back again after a reboot of the machine. The logic of the application seems to be completely broken at the moment.
