Cleanup error/error message after failed update #243
Description
When running the updater for the first time (cloning repositories) and something goes wrong, a cleanup will be attempted. This cleanup often raises an error e.g "[WinError 5] Access is denied: 'D:\\\\webnode\\\\open-law-library\\\\library-dev\\\\mohicanlaw\\\\law\\\\.git\\\\objects\\\\pack\\\\pack-bf154c865f4fce50647863222a457968f8f6d506.idx'"}
This error is then raised by the update process instead of the original error - why the validation failed in the first place
