Ads process runs into issuers request infinite loop.

[aseren]

Issue is reproduced for me on fresh master branch. The problem is that retry is happening immediatly but should has exponential backoff. Ads log extract:

This issue would only occur for a fresh install if the issuers are invalid. Changed pref to use the default ping in this situation

@tmancey can you add a test plan for this one if manual QA is required? There aren't any STR.

Retry for fetching issuers is no longer instant. It takes around 2 minutes.
