fix(rich-text-body): realiza sanitização do texto colado

O componente po-rich-text ao receber um texto colado, não sanitiza o css do mesmo, gravando informações desnecessárias na model.
Realiza a sanitização da model, para que receba apenas o valor, deixando a estilização a cargo do usuário, através das ferramentas disponibilizadas no componente.

Fixes #1872
