Testing

This MR is for showing the blue email confirmation banner when a certain exception is thrown from the backend, which only applies to new registered users that haven't verified their emails.

First use an old user (older than the email confirmation task), and you should be able to do all of the following:

• Create a post
• Comment on a post
• Vote up or down
• Create group
• Create blog
• Upload images
• Upload movies

Second, create a new user, don't verify its email address, hide the blue email confirmation banner by clicking on the X icon and try to do the same. Each time you try to do any of those, the blue banner should re-appear

I can't create a new user on the review site - when I fill out the register form, the 'join minds now' button never becomes enabled.
