**Story**
As a logged-in user, I want the ability to explicitly state whether I want hovercards or not without being part of the a/b test
**Description**
As a logged in user, my selection on beta features should always take preference over bucketing.
Failing test case:

**Detailed steps** (you need a user account with hovercards beta feature off in http://reading-web-staging.wmflabs.org/):
1. Visit http://reading-web-staging.wmflabs.org/wiki/Main_Page in a new private/incognito window and wait for the page to **fully** load
2. If you can see `Enable previews` in the footer link, then close the window and try again (goto 1)
3. Once you don't see that link, verify by hovering over [[Test]] that you can see a hovercard. That means you've been bucketed as group A.
4. Proceed to login into your no-hovercards-beta-feature user account
5. Log in and go back to main page
|**Expected**|Hovering over [[Test]] doesn't show a hovercard because on my user account i don't have the beta feature enabled|
|**Actual**|Hovering over [[Test]] shows a hovercard|

For logged in users, return here https://github.com/wikimedia/mediawiki-extensions-Popups/blob/master/resources/ext.popups.experiment.js#L76-L79 instead of falling through to returning the bucketing token.
This will break unit tests and all the browser for settings that are based on logged in users.
