Fixes connection bugs from BalancerAddress changes in #2228:

Round-robin load balancing was unnecessarily reconnecting after updating subchannel addresses. Null and not null check was mixed up.
Pick first load balancing wasn't reconnecting after updating addresses. Need to get CurrentAddress before updating addresses.
Fixes flaky HasSubchannels_ResolverRefresh_MatchingSubchannelUnchanged test.

Another way to express this might be to expose a WithAddress method on AddressSubchannel that returns a new object differing only in the address.
