1. promote content view
2. list the products in the mean time
3. the products listing fails on 404 from Pulp, because the repo was not yet created in Pulp

<pre>

With respect to #4963, it would be nice to eliminate the number of calls needed for listing the products (and ideally not calling to pulp unless unnecessary), which should fix also this issue
