Fix Chef apply provisioner to not set node_name

The base chef provisioner class will set the node name automatically
if not provided in the configuration. Since the chef apply provisioner
does not provide a node_name option, setting it will invalidate the
configuration. This checks for the node name before attempting to
use it.

Fixes #9901
