Fix/downloader not creating folder or cbz file (#676)

* Create manga download dir in case it's missing for cbz downloads

The directory, in which the cbz file should have been saved in, was never created.

* Correctly copy chapter download to final download location

"renameTo" does not include the content of a directory.
Thus, it just created an empty chapter folder int the final download directory
