ejabberd_stun: Fix 'turn_ip' fallback

Browse Source 
The 'turn_ip' option validator doesn't accept an inet:ip4_address()
tuple.

While at it, change the logic to only perform the fallback address
lookup if no 'turn_ip' is configured (analogous to the fallback
mechanism for the case where the 'auth_realm' is undefined).
