Can see "configure Gitpod App" even though I am using an oauth for my self-hosted installation

Bug description

When I try to create a project on a self-hosted installation (Created with the GKE guide), I see "configure gitpod app" even though I am not using a github.com oauth app as a way to link my github to gitpod, but rather oauth.

This seems to be a bug - it shows me the following error upon opening the pop up window where you would grant Github permissions:

{"error":"Error: unhandled request: GET /apps/github/reconfigure?account=undefined&state=eyJmcm9tIjoiL3JlY29uZmlndXJlIiwibmV4dCI6Ii9uZXcifQ%3D%3D\nStack: Error: unhandled request: GET /apps/github/reconfigure?account=undefined&state=eyJmcm9tIjoiL3JlY29uZmlndXJlIiwibmV4dCI6Ii9uZXcifQ%3D%3D\n at unhandledToError (/app/node_modules/@gitpod/server/dist/src/express-util.js:127:17)\n at Layer.handle [as handle_request] (/app/node_modules/express/lib/router/layer.js:95:5)\n at trim_prefix (/app/node_modules/express/lib/router/index.js:323:13)\n at /app/node_modules/express/lib/router/index.js:284:7\n at Function.process_params (/app/node_modules/express/lib/router/index.js:341:12)\n at next (/app/node_modules/express/lib/router/index.js:275:10)\n at /app/node_modules/express/lib/router/index.js:641:15\n at next (/app/node_modules/express/lib/router/index.js:260:14)\n at Function.handle (/app/node_modules/express/lib/router/index.js:174:3)\n at router (/app/node_modules/express/lib/router/index.js:47:12)\n at Layer.handle [as handle_request] (/app/node_modules/express/lib/router/layer.js:95:5)\n at trim_prefix (/app/node_modules/express/lib/router/index.js:323:13)\n at /app/node_modules/express/lib/router/index.js:284:7\n at Function.process_params (/app/node_modules/express/lib/router/index.js:341:12)\n at next (/app/node_modules/express/lib/router/index.js:275:10)\n at /app/node_modules/express/lib/router/index.js:641:15"}

Steps to reproduce

Walk through via loom: https://www.loom.com/share/1fe4a58f42994d0c98719c500a2d814f

1. Spin up self hosted instance
2. Connect to github.com using oauth
3. try to create a project
4. (I think this is what happened) give permissions via github
5. press configure Gitpod App
6. See error
   --> Happy to give access to the dummy github account used here.

Reproduce the flow from the GKE guide: connect GitHub through OAuth, create a project, and select “configure Gitpod App.” Start with the failing /apps/github/reconfigure request and the Loom reproduction; done means the OAuth flow no longer displays this configuration action or returns an unhandled request.
