Reproduction steps

• Start Jenkins Docker Instance
• Start GitLab self-managed instance
• connect both
• create a group in gitlab
• create a organization folder in Jenkins for the group
• copy URL of icon

Results

Expected result:

https://ci.example.com/path-to-the-icon

Actual result:

http://ci.example.com/path-to-the-icon

Seems to ignore the HTTP protocol given in the configured URL.
