delete non-empty action-set; create it again - the GUI shows it empty; add the same action: although GUI shows action-set empty, trying to add the action to the action-set from API fails with message: action already exists on action-set

Comienza en imperva_sdk/MxConnection.py alrededor de create_action y en imperva_sdk/Action.py alrededor de _create_action, usando la secuencia reproducida de eliminación y recreación como punto de entrada. Rastrea cómo se comprueba el contenido del action set después de la eliminación; se considera hecho cuando recrear el action set permite añadir la misma action sin el error "already exists".
