[chore] small changes missed in previous dereferencer.GetAccount() PRs (#1467)

* small formatting changes, rewrite fetchRemoteMedia to use separate funcs + use mutex lock correctly

* move url parsing before acquiring mutex locks

* use wrapped mutexes to allow safe unlocking. (previously i did a fucky and passed mutex by value...)

* remove unused code

* use consistent map keying for dereferencing headers/avatars
