Use hashrocket for dasherized attribute (!8775) · Merge requests · GitLab.org / GitLab FOSS

EE MR: gitlab-ee!1118

What does this MR do?

As usual, Ruby 2.1 doesn't like new hash syntax for string attributes, i.e. 'foo': 'bar', it wants 'foo' => 'bar'.

We might want to add a Rubocop for that because it's a failure we get from time to time...
