Remove link overrides from CERN Theme

Summary

The CERN theme has some link overrides for page displays of views. Remove them so that they will not interfere with the rest of the elements.

Steps to reproduce

1. Create a page view
2. Add content that includes links

Possible fixes

In common-views.scss of CERN theme there is an override of the links for the link size

    a {
      @include font-size(3.0);
      @include transition(all 0.3s ease-in-out 0s);
      line-height: 36px;
      margin: 0;

      * {
        @include font-size(3.0);
        line-height: 36px;
        margin: 0;
      }
    }

Remove it and check if it fixes the issue.
