Email DetailView template not rendering

[OGRoomService]

Issue

When attempting to go into DetailView for an email, it will not render if parent_type is null or an empty string in the database. Given that this is a possible state of the data within the database, there should be a null check to determine whether or not that part of the template should render, instead of blindly rendering it.

Possible Fix

Add a null check to the template to prevent

Steps to Reproduce the Issue

1. Have an email in the database with parent_type set to null, or an empty string.
2. Attempt to view that email record http://localhost:8080/#/emails/record/<id>
3. View a blank page
