Node delete action not working

Problem/Motivation

This is really a more general issue involving unlogical way of core BulkForm plugin operation, but I expect people to search for it by the current title.

The core BulkForm doesn't support confirmation form step in a logical way, implementation requires saving of selected results into some temporary storage in the action execute method and actually executing the action in the form submit handler.

Proposed resolution

Replacement of the core DeleteNode action plugin with a dedicated implementation and remove the core action in ViewsBulkOperationsActionManager.
