Remove placeholder methods to prevent calling methods rather than attributes.

Since we have https://dev.gitlab.org/gitlab/gitlabhq/blob/7-8-stable/app/models/service.rb#L79 makes no sense to have methods as a placeholder.

Fix importers with OCC

Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/1180

Using validates_uniqueness_of does not guarantee the absence of duplicate record insertions. When users click button "import all" it will create duplicating group in database and data integrity will be broken.

http://api.rubyonrails.org/classes/ActiveRecord/Validations/ClassMethods.html#method-i-validates_uniqueness_of

I use optimistic concurrency control for handling this situation.

Added link generation for LinkedIn on user's Profile page

This is a very very minor change. Added a generated link to the LinkedIn portion of the user's profile.

See merge request !377

Added a link_to for the LinkedIn portion of the user's profile. It felt odd to me, having this section not being an active link like the rest of the entries on the page.
