Merge lp:~deryck/launchpad/email-update-login-stuck-1036267 into lp:launchpad

[Deryck Hodge]

The code for requiring re-authentication when editing emails was only partially merged. This completes the merge to have fully working re-auth when editing emails.

This change has already landed once, been reverted, and partially landed again. This branch is to complete the merge of the work I did to force re-authentication when editing email addresses. I'm self reviewing since it's all been reviewed twice now, but the merge was messed up somehow.
