BUG/MEDIUM: resolvers: Reset address for unresolved servers

If the DNS resolution failed for a server, its ip address must be
removed. Otherwise, the server is stopped but keeps its ip. This may be
confusing when the servers state are retrieved on the CLI and it may lead to
undefined behavior if HAproxy is configured to load its servers state from a
file.

This patch should be backported as far as 2.0.
