Show "friendly" name for role instead of machine name

Problem/Motivation

When showing the role expiration field on a user's profile, the machine name of the role is shown instead of the "friendly" name. This can be hard to read, particularly if you have customized the machine name.

Steps to reproduce

Ensure that you are showing the role expiration field on user's profiles.
Create a role called "test role" (or use any existing role that is more than one word or doesn't have a matching machine name).
Assign the role to a user with an expiry.
View that user's profile page.
Note that the role displays the machine name ("Test_role", if you used that role) instead of the "friendly" name ("test role").

Proposed resolution

Display the "friendly" name instead of the machine name. A patch is incoming.
