Fixed inconsistency in enabling delete buttons

https://fedorahosted.org/freeipa/ticket/1640

On the HBAC Rules page, where the rules are listed, if no rule is selected, the "Delete" button is not enabled, and cannot be clicked on.
But edit a Rule, and Delete button is enabled in the available sections - regardless of, if an object is selected to be deleted or not, or even if there is no object to be selected to delete.

One can click on this button...but then - there is no message indicating that something should be selected for deletion for this button to do anything.

Notes:
 * fixed association_table_widget and association_facet
