Some fixes for emergency access (#4715)

Browse Source 
- Add missing `Headers` parameter for some functions
   This allowed any request from allowing these endpoints by not validating the user correctly.
 - Changed the functions to retreive the emergency access record by
   using the user uuid which calls the endpoint, instead of validating afterwards.
   This is more secure and prevents the need of an if check.
