WireGuard Android: Cached resolved host

[Heiko Friedel]

How fast is turning on and off and on?

AddressCache.java already implements a cache with a fixed TTL of 2 seconds.

A quick fix was to re-resolve with every call to getResolvedEndpoint(). 
I'm testing this for a couple of days without issues.
