[16.0][IMP] mgmtsystem_evaluation: allow update feedback and note

[luisDIXMIT]

Before, in an evaluation, when we chose a template and then changed it, the feedback and note fields weren’t updated, even if we cleared their content, because the HTML fields kept <p><br/></p>.

@luisDIXMIT I get your point with the <p><br/></p> but are you fine with the following scenario:

1. User sets the feedbacks and notes
2. User changes the template --> Feedbacks and notes are lost as they get reset to the template value.

Maybe we could have: if record.feedback == '<p><br/></p>'

Thanks for your review @max3903 now it is better, thanks!
