Debug failover to cloned manifests (#12515)

This PR, in combination with
SatelliteQE/manifester#21, addresses some of the
errors that have been occurring in CI in cases where Manifester times
out when exporting a manifest due to an upstream RHSM issue. These
changes should enable Robottelo to successfully fail over to using
cloned manifests in those cases.
