Description of problem:
If I export a CV version with non-yum repos(Satellite 6.5), the CV version gets exported. The exported has a json file but archive of contents is not seen(as expected). When Satellite attempts to tar the archive of no contets, it throws :
```
tar: Cowardly refusing to create an empty archive
Try `tar --help' or `tar --usage' for more information.
```

Version-Release number of selected component (if applicable):
Satellite 6.5.0 snap 7

How reproducible:
Always

Steps to Reproduce:
1. Create Product with puppet repo, having puppet module
2. Create a Product with above puppet repo.
3. Publish above CV
4. Attempt to export above Cv version.

Actual results:
Satellite throws improper error:
```
tar: Cowardly refusing to create an empty archive
Try `tar --help' or `tar --usage' for more information
```

Expected results:
Satellite should inform user for non-supporting of non-yum of Cv version export, untill supported.
