Passing children in the options of creating Entity will override _children

[i-tengfei]

new Entity({ children: 1 })

cesium/packages/engine/Source/DataSources/createPropertyDescriptor.js

Lines 64 to 70 in 05eebc7

	return createProperty(
	name,
	`_${name.toString()}`,
	`_${name.toString()}Subscription`,
	defaultValue(configurable, false),
	defaultValue(createPropertyCallback, createConstantProperty)
	);

Thanks @i-tengfei, I agree this behavior appears to be unintended. Would you have any bandwidth to open a Pull Request to fix?
