[Reader IA][Bug][0 tags/blogs] Infinite loading indicator on Subscription feed after subscribing to tags

[thomashorta]

Expected behavior

After going to "Suggested tags" flow inside the Tag filter bottom and returning to the Subscriptions feed it should still show the empty state (as there are still 0 blogs being followed) and not show a loading indicator indefinitely.

Actual behavior

After going to "Suggested tags" flow inside the Tag filter bottom and returning to the Subscriptions feed it shows a loading indicator indefinitely on top of a blank feed.
