404 when trying to download build artifacts using refs
### Summary
Since last gitlab update, I can not download artifacts for already existing branch.
It seems to work if I create a branch with a new name.
### Steps to reproduce
Go to : https://gitlab.com/adi90x/rancher-gen-rap/builds/artifacts/master/download?job=compile-go
### Expected behavior
Should download last artifact build
### Actual behavior
404 Error
### Relevant infos
It works if I use https://gitlab.com/adi90x/rancher-gen-rap/builds/artifacts/latest/download?job=compile-go.
Given that latest branch has been created this morning.
