fixed some failing cli tests

 - fixing 4 activation key tests
 - content host test blocked by [BZ1127629](https://bugzilla.redhat.com/show_bug.cgi?id=1127629) (skipping all of them because content host create does not work)
 - content view test blocked by [BZ1127408](https://bugzilla.redhat.com/show_bug.cgi?id=1127408)
Add a comment making this clear? It is a valid way to skip all tests, but clever enough to be confusing.
