Environment name in is displayed differently in show environment view than I registered

Summary

If the environment has a name that has more than 1 capital letter (DEV - portal), it is not shown correctly in show env page.

Steps to reproduce

• Create new environment with name DEV
• In list it shown correctly as DEV
• Click on DEV
• The title is now Dev

Expected behavior

I should see the name I entered when I created the environment.

Actual behavior

It shows capitalized variant of the name.

Relevant logs and/or screenshots

Possible fixes

Render the environtment name as is - without capitalization https://gitlab.com/gitlab-org/gitlab-ce/blob/master/app/views/projects/environments/show.html.haml#L8

I will gladly make a merge request (it's something), if this is not the intended behaviour.
