Update webgme-json-importer and use GUIDs instead of Paths for conditionals

[umesh-timalsina]

Since deepforge-dev/webgme-json-importer#10, we are exporting GUIDs instead of paths for nodes. This would mean the check

electric-circuits/src/plugins/CreateElectricCircuitsMeta/CreateElectricCircuitsMeta.js

Lines 469 to 471 in 466f7ca

	_isModelicaPin(state) {
	return state.pointers.base === this.modelicaPinState.path;
	}

will no longer work.
