core: Improve error for Auto-LB configuration failure

The ManagedChannelImpl change prevents any LB initialization failure
from producing a useless exception like:
java.lang.NullPointerException
	at io.grpc.internal.ManagedChannelImpl.shutdownNameResolverAndLoadBalancer(ManagedChannelImpl.java:321)
	at io.grpc.internal.ManagedChannelImpl.panic(ManagedChannelImpl.java:738)
	at io.grpc.internal.ManagedChannelImpl$1.uncaughtException(ManagedChannelImpl.java:144)

Instead, now it will have the expected panic behavior of an INTERNAL
Status with a proper cause.

Since the NPE in AutoConfiguredLoadBalancerFactory wouldn't mean much to
users, it now has a more explicit message.
