908012 - fixing katello-check for pulp v1

The katello-check script can be used by users, customers or GSS to do a
quick checkup of data integrity of a Katello installation. Currently it
implements two checks - it iterates through all repositories which Katello
knows and tries to find them in Pulp and vice versa. All deviations are
reported on the output.

This patch fixes the issue when it was not working because of one namespace
rename.

If you know about any kind of check that could be added, please feel free to
script it.
