screenshot of the problem

**Happens on current master AND DARGA.  Requesting Z-stream clone to be blocker.**

Description of problem:
Control -> Explorer -> Policies accordion: explorer expands to infinite recursion, doesn't let you get to policies to see/edit them.

Version-Release number of selected component (if applicable):
darga (810a94fe507f27c5f727fe4df03a0c651e1e5d9e commit), and master.

Steps to Reproduce:
1. Go to Control -> Explorer -> Policies accordion.
2. Try to expand everything e.g. the built-in Container Image policies

Actual results:
See attached screenshot.
"▾ Container Image Control Policies" expands again to:
. Host Control Policies
. Vm Control Policies
...
▸ Container Image Control Policies

clicking the last one expands recursively to the same children, ad infinitum...
(same with compliance)

Expected results:
"▾ Container Image Control Policies" should expand to specific policies:
. Analyse incoming container images
. Schedule compliance after smart state analysis

Additional info:
Right-hand side does list correct children — specific policies, but clicking those doesn't let you open the policy (IIUC it relies on selecting it from explorer).

"Good" news is that it's still possible to add a new policy (standing on "{entity} {Compliance/Control} Policies"), after which the new policy — and other existing policies of this type — appear correctly in the explorer, so you can further edit them.
Fully expanding events under them will then show "Load error" instead of event's actions (https://bugzilla.redhat.com/show_bug.cgi?id=1360818), but you can see/edit actions on right side.
