[$20] - User roles in Challenge Details page should be upadted when user registers/unregister

[birdofpreyru]

When user registers/unregisters for a challenge pressing corresponding buttons at the Challenge Details page, the user roles loaded in the page controller should be updated properly (re-loaded).
It is expected that the fix should fix the issue with forum link, referenced below.
The issue relates to the code in tc-site repo.

Hello,

When I start topcoder-app application locally and press Compete -> Development challenges (or any other challenges page) I see http://local.topcoder-dev.com:3000/404/ page and then it redirects to https://www.topcoder-dev.com/404/
Please, help me clarify steps required to have challenges and challenge page up and running!

This is because current Challenge Details page is served by code from another repo: https://github.com/appirio-tech/tc-site

If Challenge Details page is in the tc-site then this bug should be in tc-site repo?

@garntsev For the purposes of this Bug Bash we keep the track of all issues in topcoder-app repo just to have them in the same place, thus simplifying the management.
