Segv in toxav on friend going offline during active call

There isn't anything that can segv in m_friend_exists itself, but since this wasn't a debug build or anything, friend_not_valid was probably inlined and segfaulted when accessing the friendlist.

@iphydf can u write a small test case where tox_friend_exists get called in a loop in a different thread. while the main thread does tox_iterate() ?
and add/remove some other tox nodes constantly

@robinlinden its strange cause tox_friend_exists should only ever get called when u add a friend or delete a friend.
if a friend just goes offline the friendlist should not change
