UnboundedLocalError: local variable 'folder' referenced before assignment

Here's what happens when I try to run menotexport:

First, I have to manually install pdfminer.six and bs4

Then, when I run it:

`(menotexport) Cu-Chulainn:Menotexport-master holtdwyer$ python menotexport.py -pmnrz ~/Documents/mendeley_backups/backupSlot4/holtdwyer@[email protected] ~/Documents/menotexport_attempt

In short, it seems to break on the first folder due to a variable declaration issue.
