Restore fails to extract 7z archive correctly

[joelbernstein]

I have opened a PR with a fix. Essentially, the shell redirection in the 7z extract commandline has spaces where it should not have. 2 > wherever is not the same as 2>wherever.

No files to process

[joelbernstein]

After some investigation with the dry run --simule arg, I found that the "no files to process" message is because 7zr thinks it is being told to extract a file called 2. This is due to the command line construction with the shell redirection of stdout being incorrectly spaced.

Please merge and release the tiny PR I have made.
