Unable to undo a project move, leads to 404s. about support-tools HOT 9 OPEN

That certainly is a regression on our part. I am actually the person who wrote 
the feature, tested it, etc.

You on the project moved page you _should_ see a link to the /adminAdvanced tab 
if you are project owner. And, once you re-publish the project everything 
_should_ work as normal.

I'm very surprised at this new behavior and will look into it right away.

Ok, after looking through the code I think I see the problem. When we redirect 
you to that project moved page, we return HTTP code 301 moved permanently. So 
your browser caches the redirection.

However, if you publish your project after it has moved, we will no longer 
return code 301. However, you get redirected anyways because of your browsers 
cache.

I was able to reproduce your error if I used Chrome, however if I used `curl` 
on the command line after republishing the project I got the "normal" project 
homepage.

I'll update the error code we return so that other people don't get bitten by 
this behavior. But if you wish to edit your project's homepage again, try doing 
so in an incognito window and/or in a different browser after clearing your 
cache.

After publishing a project I control (game-music-emu) I still get 301s, even 
with curl (that had never before requested the project), Firefox, and incognito 
Chrome.

Since it might be a service propagation thing on Google's end I'll try again in 
a bit I suppose, but it's definitely still happening here with https.

HOWEVER, if I use http protocol things seem to work. Unfortunately Google Code 
(or the browser, not sure) seems to redirect immediately to https for both 
Firefox and Chrome, so I was only able to verify that in Konqueror and curl.

I'll also note that almost all of the links (wiki, source, etc.) after landing 
in adminAdvanced seem to work just fine even in https. However 'Project Home' 
and 'Downloads' suffer redirect errors (even in Firefox using Privacy mode).

After undoing a project move (https://code.google.com/p/saddy/), still getting 
redirects for all user pages. Tried incognito mode and logging out of Chrome.

The project owner at https://code.google.com/p/indicia/ has undone a project 
move. He says "the Google Admin > Advanced page definitely thinks it is 
republished but for me, the Sharing tab still goes to Github though all other 
pages work."

Alas, as a non-project owner, I get redirected to Github whatever I try: 3 
different browsers, Chrome with cache cleared, Chrome incognito, Postman.

I can see there is a 301 redirect. It is nearly 24 hours since undoing the move.

An update to #7. 
The project owner was able to access the Sharing tab using a browser that would 
not have cached the 301.

I find it is only the project home page where I am redirected. I can get to 
wiki, issues and source.

And an update to #8.
After a couple of days the redirect from the project home page has gone away.
