Move award emoji out of the discussion tab for MR's
This issue can be seen as part of https://gitlab.com/gitlab-org/gitlab-ce/issues/25995
Currently the award emoji in the MR view are only available from within the discussion tab. We should move this below the MR body and widget so its available while viewing any tab.
@victorwu i think this is relatively easy to do, reposition some HAML probably (perhaps adjusting some tests, so they don't fail)
@awhildy do you agree with this change? If so I think I will be able to do this myself.
