[Reader IA] Show onboarding for users with no tags or dailyprompt tag only

[thomashorta]

Fixes #20091

Ignores the dailyprompt tag when checking for the subscribed tags to show the Discover Onboarding / Choose your interests (onboarding) screens.

---

To Test:

Requirements

Create a new account to run the test (dailyprompt tag auto-injected by default) or prepare an existing account by unsubscribing from all tags and subscribing only to dailyprompt tag.

Steps

1. Install Jetpack and log in/sign up
2. Go to Reader
3. Go to Discover
4. Verify the "Welcome" message with a "Get Started" button is shown
5. Tap "Get Started"
6. Verify the "Choose your interests" screen with the tag cloud shows up

Also, test that having no tags at all shows the Welcome screen and that having other tags doesn't show it.
