with next upgrade override to_s method in User class

[kdid]

This issue serves as a reminder to update the to_s method on the user class with username instead of email. Sufia 7.3 fixes the "Works Created" link not working ( #145 ), but this change is additionally required for it to work.

Note that we have started a 7.3 upgrade branch
https://github.com/nulib/institutional-repository/tree/7.3-upgrade

but in case we don't end up using it (go directly to Hyrax, this will serve as a reminder to make this code change.

In app/models/usrs

replace

  def to_s
    email
  end

with

  def to_s
    username
  end
