Data issues with deletions

[tangollama]

My system has a patient document that is completely deleted. That delete didn't cascade to things like the imaging request queue. As a result, my imaging index route isn't rendering. We need several changes:

• cascading deletes for true deletions of patients Cascading delete for patient record #380
• flagging deletions of patients as "archived" status, as well as excluding that status from views Flag patients as archived rather than deleting them entirely #381
• better error handling for deletions in edit and index routes, such that data issues like this won't tank the system Can ember data handle failing more gracefully when underlying data is deleted? #382

Expected behavior:
Imaging index route renders, regardless of data issues.

Actual behavior:
Error.

Console is producing the following error message.

Error while processing route: imaging.index Assertion Failed: You looked up the 'patient' relationship on a 'imaging' with id 6C16C18A-1FCE-35A0-9777-47DD2F55C957 but some of the associated records were not loaded. Either make sure they are all loaded together with the parent record, or specify that the relationship is async (DS.belongsTo({ async: true })) Error: Assertion Failed: You looked up the 'patient' relationship on a 'imaging' with id 6C16C18A-1FCE-35A0-9777-47DD2F55C957 but some of the associated records were not loaded.

Steps to reproduce:
Enter a patient, enter a visit and imaging request. Don't fulfill it. Delete the patient. Go back to the imaging index route. Error!!
