When multibranch project contains branch with forward slash in the name (for example `feature/foobar`) corresponding Job gets name `feature%2Ffoobar` from multibranch pipeline plugin.
artifact-manager-s3 plugin later uses this name to generate object key:
As a result generated artifact will be placed in directory hierarchy like this:
However when we try to download this artifact via http url
%2F will be converted to forward slash by browser and request fails with NoSuchKey error from AWS.
When branch name doesn't contain forward slash everything works as expected
