Fix gRPC schema refresh not invalidating cache

The skip_cache flag in services() called reflect(), but reflect() had its
own cache check that returned early. Simplified by removing skip_cache and
always invalidating the pool in cmd_grpc_reflect, since that command is
only called when fresh schema is needed.
