frontend: unify naming convention for safe methods

Originally, safe methods were considered as methods raising
ObjectNotFound for API (mainly with session.one() method). Now
methods which returns None or ignores the error completely
are also considered as "safe".

For the sake of consistency:
- *_noop_safe -> methods that ignores error completely (they basically
  logs)
- *_none_safe -> returns None if object was not found in the database
- *_safe -> raises an exception (ObjectNotFound) if no object found
