LPS-45133

Hi Sergio,

I want to send you this pr to review since we are changing some behaviors on how permissions are workking for Message Board. We are working on a story for User being able to email reply to a Message Board post. We have found many bugs and still think the feature is not usable yet. This is the first pr of many.

For this pr, we realized that anytime someone quick reply, and reply through an email, Group Permission and Guest Permission are being set to true, which we don't think is a correct behavior. We should not assume to add Guest permissions for assests like that.

Instead, we will use a method called propagatePermission to inherit the permission from the parent MBMessage.

Let me know if this fix is okay. And if you want We can have a call to talk about the bigger picture so I can help you understand what we are trying to do.

Thanks
