Launching manual prebuild via URL keeps reloading the page

[shaal]

Bug description

When using gitpod.io/#prebuild/<repo_url>
Page keeps reloading itself every second, eventually gets to this screen -

While this is happening, open a new tab with gitpod.io/#<repo_url> (without prebuild), the screen shows a prebuild is running (terminal view), but nothing is happening.

When the process is done, opening the repo URL in Gitpod works fine, and it seems that prebuild ran successfully.

Steps to reproduce

1. Open https://gitpod.io/#prebuild/<repo_url>
2. Confirm page is reloading itself in a loop

I tried this with one of my repos: https://gitpod.io/#prebuild/https://github.com/jldec/asyncbuilder.git
It produced a redirect loop with 10 calls to /start/

This just triggered an incident because error rates went up. We should fix this before it get's costly again. 🙂

We previously agreed to deprecate this manual prefix (#/prebuild/<repo>) in favour of the new Teams & Projects Run Prebuild button. Also, the manual prefix implementation is no longer correct (it doesn't associate Projects to prebuilds, doesn't use Incremental Prebuilds if enabled, etc).

Maybe we can mark this prefix as deprecated in the docs and make it redirect to the most sensible place.

I can give this a go:
