Description of problem:
Doing "dnf -v repolist" on Fedora 23/24 ends with a traceback if -v option used.


Version-Release number of selected component (if applicable):
dnf-plugin-spacewalk-2.5.8-1.fc23
dnf-1.1.10-1.fc23

Same issue reproduced on Fedora 24 with dnf-plugin-spacewalk-2.7.1-1 from nightly-client

How reproducible:
always


Steps to Reproduce:
1. Install rhn-client-tools and rhn-setup on Fedora 23 from Spacewalk client repo.
2. Create an channel on a Spacewalk 2.5 server and create an activation key for it. Empty channel without any packages is sufficient.
3. Register Fedora client to the channel on Spacewalk server using the activation key.
4. Try running "dnf -v repolist"

Actual results:

Traceback (most recent call last):
  File "/usr/bin/dnf", line 58, in <module>
    main.user_main(sys.argv[1:], exit_code=True)
  File "/usr/lib/python3.4/site-packages/dnf/cli/main.py", line 174, in user_main

    if repo.repofile:
AttributeError: 'SpacewalkRepo' object has no attribute 'repofile'
