Updates don't work properly if "Alphabetic folders" is set to "No"

[stilvoid]

Starting from fresh (removed _Organized folder) and with the setting "Alphabetic folders" turned off, everything works and performs a full build. No alphabetic folders are created as expected:

# ls /media/fat/_Arcade/_Organized/
'_2 Region'  '_3 Collections'  '_4 Video & Inputs'  '_5 Extra Software'

However on a second run, arcade organizer thinks there are missing folders and runs a full build again (it still doesn't create alphabetic folders). I'm guessing check_if_orgdir_directories_are_missing() doesn't respect the alphabetic folders setting 🤷

Some ORGDIR directories are missing.

Performing a full build.

Of course, if I turn alphabetic folders back on, it correctly only runs incremental updates.

Might be related to #145 but I'm not sure

This may be a regression of theypsilon/_arcade-organizer#64, but I haven't had a chance to look into it. I run the same way (alphabetic folders disabled) and noticed the same behavior returning.
