Fixed self-service links.

In self-service mode the user's association facets have been modified
such that the entries are not linked since the only available entity
is the user entity.

A 'link' parameter has been added to IPA.association_facet and
IPA.column to control whether to link the entries. The link_handler()
method can be used to define how to handle the link.
