Uploading a header logo when using Object Storage for Uploads results in erroneous URI

Summary

Uploading a header image in /admin/appearance while using object storage for uploads, upload will succeed but output templates return a URI constructed with the endpoint instead of the host.

Created from https://gitlab.com/charts/gitlab/issues/429

Steps to reproduce

• Enable the use of object storage for uploads
• Go to /admin/appearance
• Upload an appropriate image
• View any page where the header image will show

Example Project

https://gitlab.helm-charts.win/users/sign_in

What is the current bug behavior?

The uri for the logo is patterned as http://endpoint/bucket/appearance/logo.jpg?...

What is the expected correct behavior?

The uri for the logo is patterned as https://host/bucket/appearance/logo.jpg?...
