using --local and --csv-path leads to deadlock

Following command:
`shhgit --config-path "G:\My Drive\Repositories\shhgit" --local "G:\My Drive\Repositories" --csv-path "G:\My Drive\Repositories"`

leads to a deadlock, without using the "CSV export" it's working.
(The error occurs no matter where csv-path is located)

```
fatal error: all goroutines are asleep - deadlock!
