ScriptPolicy scripts encounter LazyInitializationException on calling node.getSnmpInterface()

Description

Steps to reproduce:

1) Configure a ScriptPolicy in the default foreign-source definition, with its script attribute set to testing.groovy

2) Create OPENNMS_HOME/etc/script-policies/testing.groovy with the following contents:

import org.opennms.netmgt.model.OnmsSnmpInterface; for (OnmsSnmpInterface snmpi : node.getSnmpInterfaces()) { LOG.warn("Considering SNMP interface " + snmpi.getIfDescr()); } return node;

3) Provision or rescan an auto-provisioned node, or rescan a requisitioned node

Expected result:
Messages in provisiond.log corresponding to the LOG.warn in the script above

Actual result:
Exception stack traces in provisiond.log indicating the node's SNMP interfaces failed to load:

Notably, calling node.getIpInterfaces() as is done by the script in etc/examples/script-policies/example.groovy does not cause an equivalent problem. This leads me to think the NodeDao implementation might be missing some initialization for SNMP interfaces.
