Description of problem:
After generating the Inventory file, the file doesn't exist - I can't either upload it to c.r.c. or download it through WebUI. It's not present in the filesystem, either.

Attempt to upload causes:

Attempt to download causes error in WebUI:
"Path doesn't exist: /var/lib/foreman/red_hat_inventory/uploads/report_for_1.tar.gz"

Version-Release number of selected component (if applicable):
Sat 6.7 snap 13

How reproducible:
On the same system, upload worked at least once before so I'm not sure how I caused the error. Reproducer might not work for you.

Steps to Reproduce:
1. RH Inventory -> Manage -> Restart
2. After the file seems to be generated, go to Upload tab
3. Click Restart
4. Click Download Report

Actual results:
The file doesn't exist in the filesystem, can't be uploaded to c.r.c., can't be downloaded

Expected results:
Inventory file generated, uploaded to c.r.c., downloaded locally
