Undefined min, max, gt, lt values taken into consideration during validation

[jrtitus]

Describe the bug
Properties of an object are considered undefined unless set, but an explicit undefined value is taken into consideration when determining if isInt or isFloat succeeds due to the use of hasOwnProperty.

validator.js/src/lib/isInt.js

Lines 18 to 21 in b958bd7

	let minCheckPassed = (!options.hasOwnProperty('min') || str >= options.min);
	let maxCheckPassed = (!options.hasOwnProperty('max') || str <= options.max);
	let ltCheckPassed = (!options.hasOwnProperty('lt') || str < options.lt);
	let gtCheckPassed = (!options.hasOwnProperty('gt') || str > options.gt);

Examples

import { isInt } from 'validator'

isInt("5") // => true
isInt("5", {min: 0, max: 10}) // => true
isInt("5", { }} // => true
isInt("5", {min: undefined, max: undefined}) // => false

Maybe it's just my opinion, but I think that last one should also return true.
