Admin Link Redirect with Missing Trailing Slash

[taftster]

I managed to create a bookmark for the Admin page as such:

https://purelymail.com/manage

However, this does not properly work. It presents login screen, as expected, but the redirect fails and keeps you in an endless login loop. It does not redirect to the management page. Fixing the bookmark thusly:

https://purelymail.com/manage/

The (canonical) trailing slash is required for the login redirect to work. But by convention, the first link would have ideally redirected to have the trailing slash version first. A very minor thing, but possibly something to fix.
