number-Validator: null-Value validates differently for different number-ranges

[markusm7]

Environment

• Ember Version: 3.8.0
• Ember CLI Version: 3.8.1
• Ember CP Validations Version: 3.5.5

Steps to Reproduce

Implement number-validator with options:

{
  allowString: true,
  integer: true,
  // allowNone: false,
  gte: -1,
  lte: 10
}

null or undefined validate this to true (because of allowNone defaults to true)
Positive number ranges like from 1 to 10 wont behave like that. Why is this the case?
Either allowNone works for every number range or it does never if there is a range provided.

Or am i missing something?
